1. Perfect size and form factor for an HDPC. It simply could not be improved upon.
2. Touchpad works well (no scroll capability though, but see below). It is almost impossible to do a left-click on the touchpad as it is an actual pushbutton hard-click, not a tap, and that throws the cursor off every time. It does work fine in D-pad mode, and there's a separate dedicated left-click button on the left side of the keyboard.
3. Keys surprisingly responsive and easy to type. Thumb typing better than any mini-keyboard I've ever seen.
4. Rechargeable battery life excellent. Add-on software even tells you when it needs charging (but see caveat below).
5. Excellent Bluetooth range. Also, top marks to the Kensington micro adapter, range just as good as a dongle five times bigger.
6. The need to have to slide a switch to change between "media center" and "keyboard" functions could have been a huge problem, but is cleverly addressed by being able to toggle beween them by pressing Function. For example, say you're moving the cursor around a web page and you want to scroll for a moment; there's no scroll ring like on the full-size DiNovos. But if you press Function, the trackpad momentarilly becomes a D-pad (the backlighting even changes), and when you're finished and release Function, it reverts back to trackpad behavior.
7. Dedicated Windows, Media Center, and common transport keys.
1. Dedicated Windows, Media Center, and common transport keys.
These take up a huge chunk of the available real estate. As a result, there are no "F" keys and boy do I miss Alt-F4, the one combo that always shuts a program down. I could remap them except...
2. Horrible, in fact worse-than-useless software. This has always been Logitech's weak link, their terrible software. At least it doesn't crash the XL3, as I've seen Logitech drivers ruin good machines.
For example, there's a dedicated PC Sleep button. What's that for? I mean, the remote control already has one even if for some reason you decide it's a good idea to hibernate a machine that should be recording shows. Well, you can remap it, but oddly only to those functions that Vista already allows you to configure a power button to anyway (sleep, off, hibernate). So I couldn't map it to, say, Alt-F4, which would be genuinely useful. And only a handful of keys can be mapped at all; having a dedicated "Start Media Center" button (bottom right of keyboard) is nice but not a huge time-saver; but its location lends itself to being a right-click. In lieu of it already being a dedicated right-click button, the next best thing would be if I could reprogram it to do so. However, it's not on the list of buttons eligible for remapping.
The only thing the software does that you couldn't do with Control Panel anyway is the battery monitor indicator, which is neat but not worth the install. I recommend you don't bother with the CD. Besides, do you really need to read 13 pages of legal disclaimers to install a damned mouse driver?
3. As I alluded to, difficult right-click: there isn't one, and you have to hit a key/button combo, and you can't map anything else to it. Logitech should take a hint from Wacom and their tablet pen buttons and allow the user to reassign any button to any function.
4. D-pad somewhat finnicky, but that might just be mine: the down-arrow sometimes has to be hit several times to work. All the other directionals work perfectly.
5. No charging cradle. This really surprised me, as the mini's full-size brother comes with one and this unit practically cries out for a cradle. There's nothing wrong with the AC adapter (it's the same adapter as used with other Logitech mice and keyboards, but it plugs directly in instead of via cradle) but it would have made a much more professional package if you had a cradle to just drop the unit into.
6. Backlights go out too fast, and/or can't be programmed for delay. This will no doubt become less of an issue as I become more familiar with the key layout. For example, when you press or hold a Control key, the backlight stays on. That's welcome, but confusing, because the right key - and ONLY the right key - has a little icon of a [back]light, but in fact you can use either key to activate the backlight. Of course, you then have to find the Function key in the first place - better would have been to backlit the Function keys at all times the cover is open, or even an small LED dot - just something to say "push here and I'll light the keyboard up."
7. No IR capability to control monitor and audio equipment. Okay, that may be a bit much to ask, but the stock Microsoft remote (but not the Sony!) has at least some basic capability in that area.
Verdict: I've gone through two bum XL3 keyboards so I may have a different perspective, but for me it was worth it. Logitech has perhaps tried to do too much here; dedicated, non-reprogrammable buttons that attempt to eliminate the need for the regular remote control but that is just not possible - you still need the remote to watch TV for things like changing channels and skipping commercials, and frankly even if every button on the remote was replicated nobody is going to pick up a keyboard, open a lid, slide a toggle switch, skip a commercial, slide the switch back, and close the lid when they could just zap the remote. It would have been better if Logitech had kept the DiNovo mini a bit more conventional regarding its keys and buttons. A really decent remapping utility might help, but I don't know if a third-party utility would detect and remap the special extra hardcoded buttons on the mini.
That being said, the form factor can't be beat, not just for the Wow factor but simple practicality. I'm thinking about slapping some velcro on the bottom of the DiNovo mini and the remote control and hiding them both under the overhang of my coffee table. Sweet!
