IF you've been around a PDA for more than a few seconds, you understand that this device is a great invention. It has very little disadvantages. But one distinct disadvantage is the fact that it's almost impossible to write more than a few words on the PDA's keyboard. It's too small and completely un comfortable. That why the PDA keyboards were introduced to the market. It's a simple solution. You get yourself a portable, wireless keyboard, sync it with your Palm iPAQ, or whatever PDA you're using and that's it. You now can type all day long like you do on your PC and get all that fed right into your PDA for later use. And the keyboards are not expansive - less than $50 will get you a great wireless keyboard that will serve you well.There are quite a few keyboard models on the market, and it's best to do a little research before buying. You'll be wise to check a few parameters before you buy yourself a PDA keyboard, to make sure you're choosing the right product. 1.Is it wireless? Most keyboards on today's market are wireless. Sure you can get one with a wire but it makes no sense. Why limit yourself? You'll want to use the keyboard in all kinds of situations, maybe with the PDA tucked down inside your handbag? Go for wireless - the price gap in insignificant.2.Is it comfortable? Not all keyboards are nice and comfortable, and not all of them are agronomic. If possible, try to use a few keyboards before buying. Choose the one that is the most comfortable for you, even if costs a little more. You'll thank yourself later.3.Does it allow you to type as fast as you like to? If you chose a keyboard that is comfortable for you, typing fast will be easy.4.What kind of power source does it need? Most keyboards need a few standard batteries to operate. Make sure your chosen keyboard doesn't need anything exotic.5.Installation - make sure the installation process is easy. Make sure your version of the PDA and it's Operating System support this keyboard. This sounds trivial but you'll be amazed how many times people over look this.Getting a portable keyboard will make your life a lot easier that having to get along with out one. In fact, many users claim that buying a $45 keyboard to add to their PDA saved then investing $1200 in buying a new notebook computer. So consider getting that keyboard - you'll never understand how you managed without it.

5 Tips For Finding The Best PDA Phones On The Market
By: Ron Heller
The PDA phone revolution is here. Only a few years ago, many of us used to carry around a cell phone as well as a PDA, and suffered form the "too much a handle" syndrome. The PDA as well as the cell-phone manufacturers saw this development, and sensed that people need something else. Their answer was to come out with a PDA phone, or a smartphone. This sophisticated device integrates a PDA with a cell phone and allows you to stay on to of things without getting over-whelmed. The smart phone will enable you to:1. Keep one calendar instead of two.2. Talk to people on the phone and check things on your email on the web at the same time. This saves a lot of time and returned phone calls.3. Carry less4. Upgrade just one device instead of two, when it's time to upgrade.5. Look sharper than ever!So after we talked about the many advantages of having a smartphone, how do you find the Best PDA Phones and choose the one for you?There are quite a few smartphone manufacturers - iPAQ, Palm-Treo and BalckBerry to name a few.When ever you look for a PDA phone, pay attention to theses parameters:1. Is it compact and light? some smartphones are just heavy and awkward to handle. You don't need that. Go for a light and thin device that won't be a burden.2. Is it easy operate? Some PDA phones have complicated menus that require you to invest a lot of effort. Take a good look at how the PDA phone in operated and look for one that is easy. 3. Does it use standard software? - most smartphones are. But just check to be sure. You don't want a smartphone that is "spoiled" and needs special software and accessories to operate at a basic level. For instance, prefer one that uses an operating system like the Palm OS.4. Is the phone working well? There is a fine balance between the PDA and the Phone parts in any phone PDA. The Best PDA Phones balance that well and both parts work perfectly, and are fully integrate. Make sure yours does.5. Do you feel comfortable with it? Perhaps the most important one of all. If you're not comfortable with the device, it deosn't really matter if it's considered the best in the market, does it? Choose the one you feel good about.Taking a good look at the variety of smartphonmes as well as reading reviews and consulting with owners is good practice. It will ensure you come up with the Best PDA Phones on the market, from which you can choose yours.

PDA Memory Cards - 7 Tips On Using Them To Improve You Bridge Media Experience
By: Ron Heller
PDA Memory Cards are a very popular means of immediately enlarging the memory capacity of a PDA. Most of the PDA Memory Cards that are in use today are of the SD memory card format, and their capacity ranges form 16MB to 1GB. The 2,4 and 8 GB cards are now in development, and are expected to penetrate the market during 2007 and 2008. Quite impressive for a memory card the size of a post stamp. The use of an SD memory card is great for installing additional software on your PDA, or storing more data on it. But it also enables your PDA to participate in what's called "The Bridge Media" concept that the SD memory card creators had the vision for.The meaning of Bridge Media is that the SD cards can offer a way to connect many sorts of appliances trough one small memory card, without the need to use any interpretation. Let's look at an example:You shoot a video clip with your digital camera. You will store the video clip on your SD card which is supported by the digital camera. After that, you can take the memory card out and plug it into your PDA. The video clip is immediately shown on your PDA, without the use of any other device. You didn't need your PC's intervention in doing this - both your digital camera and your PDA know how to read and write data to and from an SD card. The nest thing you can do is, say, change the video clip is some way sing your PDA (like adding titles). You can than save the new video clip to the memory card and take the SD card to a video camera. The video camera can now read the new video clip and display it on it's screen or on your television. Here's another example:You have an important phone call on your cell phone. Your cell phone supports SD memory cards so it's able to record the call. You can later save the phone call audio file on to your PDA memory for future use. As you can see the possibilities are endless, and memory is something you can easily move from one appliance to the other thanks to the flexibility of PDA Memory CardsAnother thing to remember is that the DS memory cards have very fast read/write speed of X133. This is possible due to the fact that no physical component are active in the read or write process, and the memory is completely electronic.

A Buyer’s Guide to Flatbed Scanners
By: Microtek Lab Inc
A Buyer's Guide to Flatbed ScannersFlatbed scanners generally deliver the best combination of quality, flexibility, and usability in scanning. They can be used to scan different kinds of media, including photos and film (with the additional use of a transparency adapter); they can be used to scan text for OCR and document archiving; and they can be used to scan material of varying sizes and thicknesses - from small postage stamps to large mechanical blueprints and 3D objects. To determine the flatbed scanner for your needs, this buying guide covers some of the more important flatbed scanner specifications that you will need to know.Bit depth and color passPractically all scanners today are single-pass types with 48-bit color. Gone are the scanners of yore that required three passes to capture the full RGB (red, green, blue) color information from an image in individual, painstakingly slow takes. Gone too are 24-bit and 36-bit scanners that proved sufficient in the past for delivering up to 68.7 billions of color.Today's single-pass, 48-bit scanners are fast and can theoretically capture up to 250 trillion colors - clearly more color than the human eye can distinguish or what monitors and printers can reproduce - but impressive nonetheless for the promise of yielding hues as close to life as possible and delivering smoother color gradations. Ignore all but single-pass scanners when shopping for a flatbed, and aim for 48-bit color as well. Consider lower-bit models (such as 42-bits) only if your scanner of choice has other specs that a higher-bit counterpart may not have - such as patented technologies and special features - that more than compensate for the lower bit depth of your selected model.ResolutionThe resolution of a scanner determines the level of detail that can be captured; the higher the resolution, the sharper the scan will be. There are two types of resolution: optical and interpolated, with optical resolution being the more important spec, as it relates to the scanner's actual optics and amount of information that it can sample. The interpolated resolution of a scanner is helpful only in specific applications - such as scanning line art, where higher resolutions can even out jaggedness and produce smoother contours.Most flatbeds today feature respectable specs for optical resolution, ranging from 2400 dpi to 4800 dpi. Any scanner with such resolution figures would prove a respectable choice, since these specs are more than capable of delivering sharp detail or enlarging images for most print applications. Remember, too, that scanning your images in the full resolution of the scanner is likely to yield file sizes of unmanageable proportions - without delivery any discernible benefit towards increasing image clarity or quality. So forget the resolution wars of the past when manufacturers trotted out their resolution specs to trump their closest rival. Instead, look for other features today in flatbeds that may be more important for your needs, or consider the resolution spec TOGETHER with these other features when choosing your choice of flatbed.CCD vs. CIS Sensor TechnologyImage sensors in flatbed scanners can be of two types - CCD or CIS. Scanners with CCD (charge-coupled device) sensors use a system of mirrors and lenses for redirecting light reflected from the original document to the CCD array. Because of the required optics, CCD scanners are more expensive to produce and result in bulkier scanners, compared to their CIS counterparts. The image quality produced by CCD scanners, however, is far superior to that produced by CIS scanners.CIS, or Contact Image Sensor technology, is a more recent development in which the sensor array lies just under the scanner bed, so that the sensors catch reflected light directly. Since CIS scanners do not need a complex optical system, they are cheaper to produce and are smaller in size, resulting in portable, lightweight models that may be prove ideal for cramped desktops. CIS sensors also contain on-board logic that consumes less power than CCD. But because the on-board logic utilizes space that would normally be used for the mirrors and lenses in a CCD to sense light, scans from a CIS scanner are lower in quality. As a result, most people tend to forego the slight savings that can be obtained from a CIS scanner in favor of getting higher-quality CCD models instead.Connectivity & InterfaceMost consumer-level scanners today will feature USB ports - either Hi-Speed USB (USB 2.0) on more recent models, or the earlier USB 1.1 standard. Hi-Speed USB is backwards compatible with the USB 1.1 and has a data transfer rate of 480 megabits per second (Mbps). Higher-end scanner models are likely to include the FireWire interface as well, allowing scanners to be used in advanced, professional such as audio/video transfer and data storage. Scanners with either USB or FireWire interface are hot swappable - which means the scanners can be plugged or unplugged from other devices to which they are connected without having to turn the scanners off and on. Older scanners will include SCSI or parallel ports, but you shouldn't have to consider these legacy-type models - unless you are using the scanner to connect to older computers. When shopping for a flatbed, any scanner with a Hi-Speed USB port should be purchase-worthy, but consider getting a model with dual Hi-Speed USB and FireWire interfaces to expand your range of possible connections to many other devices and peripherals.Scan SpeedSpeed specifications in flatbeds are hard to determine - unless the scanner manufacturer provides the specs or the exact conditions in which material is scanned. Scan speeds can run from seconds to several minutes, depending on a wide variety of factors. For instance, to compare scan speed between two comparable models, one will need to know the size of the material being scanned, the resolution setting, the interface being used, and the processing speed and power of the computer to which the scanner is connected. Check speed claims carefully if these are made at all; it may help to do an actual or sample scan with the model of your choice, and see if you are satisfied with the speeds of the preview and actual scans. You could also check to see if your flatbed model has been reviewed in computer magazines or sites and rated for speed, as benchmark tests may give a more comprehensive picture on how fast the scanner runs.Size of Scan BedMost flatbeds today will start out with a standard scan bed size of 8.5" x 11.7", approximating the dimensions of a letter-size image or document. From there, various bed-size configurations could come into play, including 8.5" x 14" to accommodate legal-size material, and 12" x 17" for large, tabloid-size scanning. It's usually a good idea to consider a flatbed with a bed size that's beyond the bare minimum - in this case, larger than the barebones 8.5" x 11.7". Not only can you fit larger-sized material onto the scan bed, you can also group several smaller pieces on the scan bed and perform batch scans (scanning in groups) to save time and effort. Dynamic RangeThe dynamic range of a scanner measures how well it can capture the tonal range of an image, ranging from the brightest highlights to the darkest shadows. Dynamic range is measured on a scale from 0.0 (perfect white) to 4.0 (perfect black), and the single number associated with a scanner indicates how much of that range it can tell apart. The minimum and maximum density values that can be captured by a scanner are called Dmin and Dmax, respectively. If a scanner's Dmin was 0.2 and its Dmax was 3.0, then its dynamic range would be 2.8.While dynamic range is a term often bandied about, in truth the spec is more important for film scanners used to scan slides, negatives, and transparencies - as these types of media have a broader range of tones compared to photos, and for which a scanner's higher dynamic range can make a difference. Most flatbed scanners will have a dynamic range of 2.8 to 3.0, but don't be surprised if you can't find it in the specs, as this is not critical information needed by the average user looking to scan photos or prints.SoftwareIn selecting the scanner of your choice, consider the software that comes with it. Software will always include the scanner's own driver or scanning software, as well as a host of complementary programs such as image-editing software like Adobe Photoshop to which the scanned image is delivered; optical character recognition software like ABBYY FineReader Sprint for text scanning and OCR; color calibration software for higher-end scanner models; and even photo-repair software like DIGITAL ICE. Check for extras as well, such as proprietary or exclusive technologies.

How To Keep Your Computer Running At Full Speed
By: Gregg Hall
Have you noticed your computer processing a little slower than normal? Maybe you can't get your e-mail as quickly as you used to. Or maybe you just want to put your foot through the monitor screen because it keeps freezing anyway and you're not getting anything done. Save your loafers. In actuality, you might need a little memory boost. Every computer relies on RAM, random access memory. RAM resides on your computer hard drive, so to boost your RAM, you first need to take a look at your hard drive and then get to work cleaning up your computer. Routinely checking and cleaning your RAM will keep your system running more smoothly. Just a few different checks will maximize your computer's performance while you sit back in your ergonomic chair and think about your next project instead of the frozen screen in front of you. To make your RAM bigger and improve the speed of your computer, just increase your memory. You can do this a couple of ways. Defrag your computer to rid it of unneeded files. Doing this will make everyday processes like a word processing program or your accounting program boot up and run faster. You won't find yourself chewing your nails in anticipation for the next window to pop up. Maybe you need to purchase another hard drive. You can install it easily and with little extra cost, and doing so will maximize your computer's speed. You'll find yourself blown away by the lighting quick speed of programs on your computer. Those of us that use our computers regularly will greatly profit from more memory. Two hard drives really will make a difference. The wimpiest hard drives usually come with the computer; so if you're still using your factory hard drive, buy another one. To install a new hard drive, you only need a screwdriver. You can find the right hard drive by asking a technician at your local computer hardware store. They should point you in the right direction. Then just follow the instructions in the package. Another hard drive might not only save you the frustration that a slow computer causes, but it will save you the headache of lost files. It gives you another places to save your files, a virtual additional filing cabinet. This saves you stress in the end and allows you to sleep better at night and work better in the day. As you work with your hard drive, spend time cleaning out your files as well Delete what you don't need and then back up what you do want to keep. There's nothing worse than finding yourself in the middle of an assignment with a blank screen and the hum of a dying hard drive in your ears. So do what you must to keep your computer in tip top shape and ready for your next task.

Advanced Techniques For Unclogging Print Heads
By: Richard Sherland
WE will begin with the simple easiest methods and then get into some of the ways the professional printer tech gets them unclogged.Dealing with a clogged print head can be frustrating but this is no time to get into a hurry. Cleaning solvents can take many hours to do the job. And remember your trying to save the life of a printer. If all fails you printer may be ready for the printer graveyard. I'm talking about printers with the built in print heads here. It's probably best to explain the different types of printers now.There are two rough categories of printers one with the print head built into the printer. For example Epson some Xerox and Canon .The other are Hp and Lexmark, which have the print heat built into the cartridge.On most of the printers with built in print heads it is a major job to remove the print heads so all of our cleaning methods are with them left in the printer.Most of the clogs that occur while you are printing aren't severe. The ones that are in many cases tough are when the printer has been sitting for a long time without being used. In this case the ink can dry as hard as a rock.The first thing to do is to run the print head cleaning cycle 3 to 5 times. If you don't know how to do this check your manual or check online for a manual if you don't have one. After running the cleaning cycles, check the print out for the slightest change for the better. If it's getting better let it cool for a few minutes and continue. If it stays the same or gets worse move on to the next method.Epson recommends running the cleaning cycle several times then printing a test page. Don't print a test page after each cleaning cycle on a tough clog. It does waste more ink this way but is necessary when you have one that is badly clogged.If you still have problems its time to move on to more advanced methods. On Ebay you can purchase a Cleaner Called E.K.S. in small quantities. I'm in no way affiliated with this company by the way. Just type in Epson head cleaner and it will come up. This cleaner will work for all other brands also. I recommend that you keep some of this on hand if you have this type of printer.Normally if you open the printer cover you can't move the print heads around. So here's what we do. Turn on the printer and watch the print heads move around while they are still moving unplug the power cord. Now you can move the print heads back and forth with your fingers. Take a piece of paper towel and cut out apiece about 3 inches long and 1 and a half wide. Fold this accordion style until you have a strip about one half inches wide. This isn't critical.Put some of the head cleaner on the paper towel and lay the paper down flat and move the print head until it's over the paper. You may have to work at this there's not too much extra room to get the paper under there. The wet towel will stay moist for several hours and keep the head wet with solvent. This is one of the most powerful ways of getting the job done.Check the towel every few hours and if it's dried out apply a little cleaner with a syringe. Let it sit at least overnight for a real stubborn clog. Leave the printer cartridges out because it can wick all of the ink out of the cartridge. Apply a little of the solvent to the little pins that go up into the cartridge to keep this area wet also. Use the cleaner sparingly as you don't want to get this cleaner down onto the circuit boards. This would cause a short and maybe ruin the printer.When you get ready to run a print test remember that it may take awhile for the print head to get filled with ink so it might not print on the first tries even if it's unclogged. There is one other method that techs use. Get a short length of one-eighth inch clear plastic tubing at a hardware store. Hook this onto a syringe. Slip the plastic tubing over the little pins the ones that go into the cartridge. Then push in on the plunger to try to force air through the print head. Always push the air through don't try to suck air through by pulling on the plunger.If the printer is under warranty you could just send it back for repairs instead of going through this. But if not under warranty it will probably cost you more than it's worth to send it to the factory, as they will many times replace the print heads. If you don't have any of the recommended cleaner and it's an emergency you might try a solution of 50% distilled water and 50 % ammonia. Well good luck I hope this helps.
