Background: I use a HP 4700 series PDA with a Pocket PC OS. I type 50-60 wpm. This is my first portable keyboard purchase. I have used the product for 3 days.Cons:1. PDA stand is hard to remove from keyboard2. Center folds do not lock flat3. Keyboard casing is prone to smudges (but very durable)4. Discovery/power button needs a stylus to be usedPros:1. Full size keyboard including separate number row2. Easy and compact keyboard folding3. Driver support for international keyboards4. Adjustable repeat key rate and time delay to repeat. Repeat rate is very fast at top setting.5. No delay after key press. This keyboard keeps up flawlessly with my typing speed.6. Keyboard links securely to PDA without having to re-type code each time. Once password connection is set up, re-linking after either device is turned off is fast (just press any key on the keyboard).7. Keyboard functionality similar to windows: I can switch easily between programs by pressing Alt-Tab. Accents, grave accents tilde "n'"s, inverted exclamation marks are typed just like on desktop computer.8. Programmable keys for launching programs and well thought out built in short cut keys. Special quick launch keys for calendar, contacts, e-mail and internet are off to the side.9. Keyboard turns off when you slide endgrips into storage position. While it is small, a green LED light indicates when keyboard is consuming battery power.10. Convenient stylus well for alternating between stylus use and keyboard use. Stylus well also present on the left for left-handers. (Keyboard and shortcut keys actually make navigation without a stylus convenient and easy. Switching between open programs on a PDA is much easier with the Alt-Tab keys than with the stylus)11. Unbelievable range: I can type from a separate room through a cople of walls and around a few corners. The single press of the shift key seemed to capitalize unintentional 3-4 letters at this range, but I really wasn't expecting to see anything at all. Use around other wireless devices (phone and router) did not interfere with transmission.General Comments: I find this keyboard to be an excellent product and productivity enhancing tool. Installation was flawless. Some tasks such as switching between programs are actually easier now. While I can type with the keyboard on my lap, the sides tend to flap a little. The natural downard pressure of the fingers typing makes the keyboard more straight. Thus this is a moderate nuisance that does not entirely disable the ability to type with the keyboard on the lap. The folding PDA stand is difficult to remove from the back of the keyboard. After several tries I seem to have a 75% reproducible method of doing this easily. Sometimes I am afraid I will damage the keyboard by either taking the stand out or by replacing it. A polishing cloth comes with the case to remove fingerprints which is nice. Packing the cloth in the neoprene case with the keyboard is a little tricky without crumpling the cloth (zip the case 35%, insert the keyboard then the cloth, straighten cloth under neoprene case then zip remaining case). For the first couple of days I thought I had to type the password on the device and PDA each time to synchronize the devices. This was getting a little annoying. Then, after reading the owners manual on the CD (which is much more complete than the brief instructions provided on paper), I found this wasn't necessary. Just pressing a key does the job after either device is turned off. The keyboard keeps up with my typing speed. The range on this device is absolutely unbelievable. I was able to type approximately 50 feet away from my PDA on a full battery! I am curious to know if other users find this reproducible. I don't have a good feel for battery life yet. There is no apparent interference from use near other wireless devices. The device is practical to use. Another inconvenience I find is that picking up the keyboard to move to another room is a little clumsy since the keyboard doesn't lock in the center. Sometimes this will result in a few unwanted keypresses during transport with both devices on. This is particularly a problem when I have many other things in my hand. Overall this device has boosted my productivity, and I am extremely pleased. I was planning to buy an ultraportable lap-top, but this is an inexpensive solution to turn my PDA into essentially the same thing from a word processing perspective. Just wish they had a good database solution for PDA's.
