Summary: A step backward
Review: I investigated one of these as an alternative to the Sony KB100 and the now-discontinued KB11.
Where the KB100 folds in half and the KB11 folds in a now-familar "W" shape, the Wireless Universal (WU from here on in) has three components -- a keyboard that folds in half and a third component (housing the PDA support and infrared arm) that flops down over the folded keyboard. The result is a box that's significantly thicker, wider and longer than either of the other keyboards.
It's also more complicated. Either of the other two require that you unfold them, pull out the PDA support and then dock the PDA. This one requires you to Unfold the support component, then unfold the keyboard, then tilt up the support, then open and position three wire loop PDA "locators" then unfold and position the IR sensor arm. Complicated, time consuming, and more stuff to break.
Unlike the KB100, there's no way to recharge your PDA while you work -- no port for the AC adapter -- and this keyboard seems to consume PDA battery faster than the other two keyboards mentioned.
In operation, you need to be very careful that you start the keyboard software after you get the PDA in the cradle, and you should avoid moving the PDA out of the keyboard with the keyboard software still running -- some PDAs have experienced lockups that required a hard reset to fix. If you're sitting in a Starbucks where anyone else is using IR with a laptop, cell phone or another PDA, you can get spurious characters appearing on your system. The keyboard touch isn't bad, and the travel is adequate, but the right shift key is small, and in a place where it's very easy to hit another key if you're not used to the placement.
All in all, this is a clunky replacement for the very good Targus Stowaway series; Targus has evidently declined to purchase the version of the Stowaway from ThinkOutside that supports the newer Clie models and seems to believe this will save them from having to support a different keyboard for the widening variety of PDAs. Unfortunately, the've moved *away* from portability into an unnecessarily larger size and into complexity with this item, and mine went back after the second day. It's now between the ThinkOutside Stowaway XT and the Sony KB100, with the ThinkOutside Stowaway for Clie a possible third.

Summary: Not the Best
Review: I purchased the wireless version after I upgraded my iPAQ to Windows Mobile 03 software and couldn't get the drivers on my old Targus keyboard to work anymore. Too bad. Overall the keyboard isn't bad. It works fine. My biggest problem with it is the size of the keyboard. It's noticeably smaller. I use it primarily to take notes in meetings and am constantly hitting the wrong key because it's just not sized like a regular keyboard. That was not a problem with the other one.
My other complaint is I would rather have the arrow keys back and get rid of the "mouse". I thought it was a great idea, but it's really more cumbersome in reality than it's worth--at least for me.
My last complaint would be to beware Targus' customer service. I tried getting help when the drivers on the old keyboard quit working and got absolutely no response from them. If you end up having a problem with your keyboard, don't expect any assistance from Targus.

Summary: Takes some getting used to
Review: I really enjoy the portability of this keyboard. At its reduced price, it was definitely worth the money and I wish I'd gotten it sooner! I agree with another reviewer that it would be much better if it had arrows because I do not see the point of having a start button when there are no arrows to maneuver through the menu and the cursor has to be moved across the entire screen. Other than that, the keyboard is a little smaller than a normal one which makes my fingers scrunch up a little and the infrared arm will sometimes move but it doesn't happen much and overall I really enjoy it! I would definitely recommend it to any student as a great affordable, more compact alternative to a laptop.

Summary: `good `keyboard
Review: I really enjoyed this keyboard. I recently lost mine, but I liked it so much I'm going to buy another one!It worked perfect with my Clie... But there are drawbacks: - The right shift key is smaller than the left. Right next to the key is the rarely used ` or ~ key. I'm always having to edit this out and turn it into the capital case letter I wanted it to be. I would have rather had this key moved way over to the left. I don't think it would be a problem over there.. or even somewhere as a mini key! - The "Done" key is too close to the return key. I'm constantly having to reopen a memo - It would be nice to have some sort of control over the keys. Maybe like a keyboard hack. Then I could change the location of certain miss-hit keys and have no problem. Despite these annoyances I really enjoy this keyboard. If want to use your organizer to enter large amounts of text and want to be able to use it on your next PDA, this is the best option. Hopefully though, Targus will make a few minor changes in their next model.

Summary: With a Toshiba 3755
Review: I think the above 5 Star reviews are accurate. My caveates are:
1) no page down, but the cursor/fn shortcuts are adequate.
2) tiny right side shift key (req. pinky)
3) broken up space key requires using left or right finger tip
4) driver CD locks up computer, but the Targus.com site installed the drivers effortlessly. Pros:
1) Infrared error free and hopefully low-battery consumption
2) Folds up nicely, with care required for most Chinese plastics (apparently Clinton did not 'share' our plastic technology)
3) Price . . . as affordable (through Amazon) as a standard KB
4) Ample preloaded shortcuts Conclusion: This is an inexpensive accessory for your PDA/Toshiba PPC which turns your palm device into a subnotebook. Like any non-standard keyboard, it takes some adapting, but its accuracy will dispell the intitial adjustment. Suggestions to Targus:
Only two - 1) hinge/slideout a Symantec Touchpad and replace the cursor with a 4-way toggle plus page up/down, end, home keypad. They can be reduced in size to fit, as they are not a usual touchtype item. And 2) Figure out a way to make the space keys raised and spring loaded for using our thumb.

Summary: Works with Ipaq 2215
Review: I use the the Targus with an IPAQ 2215. I find that's it's indispensable, but quirky. The cradle (rubber covered stiff wires) works best for "squared" PDAs (my Ipaq has a rounded bottom and can rock), and you may need to tilt the PDA for the infared bar to point into your IR reader. (If you use a flip-style case, you will have to remove it for the IR bar to beam into your IR reader.) I'm not crazy about the cursor arrow key (it's not a regular cursor "arrow" key), and the split-up space bar keys do sometimes have problems. As another reviewer remarked, downloading the drivers from Targus.com is much easier than using their included CD-ROM.

Summary: Universal?
Review: No way! It does not work with the Toshiba e405, that's certain. Cannot align laser with infrared port located at the bottom righthand side of the PDA -- unless, of course, you are willing to hold it with one hand and type with the other. I'm sending it back.

Summary: One keyboard to rule them all!
Review: One of the most important design I look for in PDA keyboard is the key size. The Targus keyboard has the standard QWERTY key size (for alphabets only though), making typing a breeze. The key size and the touch feel is similar to normal laptop keyboard. You should not have any problem using this keyboard if you have no problem typing on a laptop. The absence of arrow keys is compensated by an 8-directional arrow key. Pressing one of the directional key while holding down the Fn key gives the same navigation functionality as the normal arrow keys. So is the case for Ctrl+{ArrowKey} for navigating between words. While some of the keys are pretty small (R-shift, Backspace, Tab), I have not had major problem adapting to them. The only complaint I would have for this product is its relatively big folded size and weight - it's quite impossible/uncomfortable to fit into pocket. Nevertheless, this is essentially just a trade off for having full-size keys. Also, the price may be on the high side compared to other products in the market. Side note: There are also some Taiwanese OEM keyboards in the market that copied Targus's IR arm design, selling as cheap as $40 - although these products have much smaller keys and a less sturdy build. All in all, I think this is a great product comparing to other keyboards available in the market. Like any other IR keyboard, this will cater for the current PDA owned, and (hopefully) the future models. P/s: after finish typing this review on my Targus keyboard and Dell Axim X5, I experienced slight strain on my wrist - I believe this could be due to the somewhat rigid posture I have to maintain to adapt to the size of the keyboard. This would be a common problem for usage of PDA keyboard nonetheless, and could be worse if it were to be a smaller keyboard.

Summary: Targus Universal Wireless Keyboard - A Great Buy
Review: The above review by "An Electronics Fan" for this product is very misleading. The keyboard has none of the flaws that he/she mentioned. Of course I can only speak for the Pocket PC, but I find very litte wrong with it, and can positively say it is the best IR keyboard out there. First of all, yes, it does not have cursor keys. But it has something better, a mouse button. This lets you click around the screen without need to use the stylus at all. If you're like me and use the cursor keys to go back and correct mistakes, it still does this, you just hold the FN key and use the mouse which makes it act EXACTLY like cursor keys. There is no "elf" effect. Unlike the wireless keyboards that use mirrors, and go very slow and drop letters, the Targus keyboard does nothing of the sort. It's just like a desktop keyboard, in that everything appears as soon as your type it and there are certainly no dropped letters. There is one thing I would have liked, which would be the "Home" and "End" keys which I use quite frequently. It does have a key combination (Ctrl+Mouse Arrows, I believe) which lets your just from word to word, which does it almost as quickly. That is really the only thing that could be improved. This is definately the best keyboard out there, and the one I will be using for probably any Pocket PC I buy. Since my Toshiba e310 doesn't have a "plug-in" keyboard for it, IR was my only option. After being absolutely disgusted by the iConcepts IR Keyboard, this one is very welcome. No need to line it up, a constant connection, ability to use it in your lap and in a car, along with many other things. I would recommend this keyboard to anyone who is looking to buy one.

Summary: Design Flaws, Not Supported for Many PDAs & Poor Support
Review: The concept of a wireless IR keyboard that can work with multiple PDAs, as well as Pocket PC & Smart Phones is great. But the execution by Targus is poor, especially if you don't have a popular PDA model that is approved. Unfortunately, I found my Pocket PC Phone is "pending" approval - and so are dozens of other models. (But when you first see this in a store, you see "compatible with most PDAs..." and how are you supposed to know differently?) Although this keyboard may support most PDAs in terms of quantity, it actually may not support most "models" of PDAs. [. . .] I've contacted Customer Support 3x's over the past two weeks on a number of matters, as outlined below, and get no solutions or answers, just form responses. In particular, they cannot let me know when my PDA will be approved. However, even if your model is approved, there are some things you should know. One item that drew me to this keyboard are pictures of it operating a PDA sideways. For taking notes in meetings, this can be very useful. Some reviews even indicated that the sideways software was included. Don't be fooled like I was. Not only is sideways software not included, but Targus does not indicate 3rd party vendors on their website, nor will customer service recommend what to use. The sideways software I tried, Nyditot, had conflicts and wasted hours of my time. Customer support alerted me to the small asterisk and print that referred to their picture of a PDA sideways on their keyboard that says "3rd Party Software Required." OK, if they can't provide you with a trial version, can't they at least let you know what sideways software may work with it - if anything does? Problems that I encountered follow: 1) The back-light doesn't come back on when a key is pressed. Instead, the screen must frequently be touched or backlight set always on. 2)The "Task & Find" button on the far left - one of the most potentially useful features - has a conflict and does not work. 3) It is always necessary to "enable" or "disable" the keyboard software and you MUST select "disable" before taking the PDA off the keyboard. Otherwise, it can freeze your PDA. If you forget this, and take your PDA without your keyboard perhaps to lunch, the only way you might be able to unfreeze your PDA is to do a hard reset. 4) The keyboard software pops up on the PDA from time to time, for no reason. Granted, some of the issues above may be limited to non-approved PDAs, but I doubt all are. Finally, regardless of whether your PDA is approved, the keyboard layout has certain faults, as pointed out by one or two others. In particular:
1) The space bars are badly located and too small.
2) There are no cursor keys
3) Although there is a "mouse" of sorts, because it is a little awkward to use, there should at least be at least two dedicated cursor keys (left/right) & with Fn (Up/down).
4) The backspace key is small and awkwardly placed.
5) No Page Down & Up keys.
6) No Home and End keys The product manager for the Wireless IR Keyboard dropped the ball on what could have been a "must have" product for PDAs & PocketPCs. I especially believe the advertising on the packaging is deceptive regarding the use of its stated compatibility with "Most" PDAs.. and the picture of a sideways PDA on the keyboard is very misleading. You can get a much better price on this keyboard here at Amazon than in the stores, but be sure to consider the issues. Personally, I'm returning mine and believe this device needs to be improved- or another vendor will have something better. I'm very disappointed in Targus, not only due to poor customer support, but in rushing a product out before being ready and making deceptive claims.
