I was looking for something wireless that would work with my KVM switch (IOGear) and be compatible with Windows AND Mac OS X. This works great out of the box with both. The size is great and it has a very low profile. Two fold out legs provide two fixed angle options. The solar aspect of this is an "it's about time!" feature and seems to work marvelously well -- even in constant low lighting.

The description "Solar-powered keyboard: No battery hassles ..." is a bit deceiving though. The keyboard IS in fact battery powered and the solar panels charge the battery. The single coin-cell battery is user-replaceable, although it is really difficult to get out without marring the keyboard and there is a big sticker on the battery that says not to replace it. A button on the keyboard shows a happy or sad indicator regarding the amount of light being received. Mine is always a "sad face" due to low lighting, but the battery has remained charged at 100%. There is an easy-to-access on/off switch right on the keyboard if you need to conserve more.

The keyboard keys are similar to most laptop style keyboards (square/flat), which I personally prefer. The Windows and ALT keys are a bit on the small side (they're the same size as regular letter keys) and there aren't any caps/number/scroll lock indicator lights. Windows software is available for on-screen display though.

The only thing I'm not crazy about is the white border and underside of the keyboard. It looks okay, but I imagine it won't age well.

Lastly, as a casual gamer, I can confirm that this keyboard supports multiple, simultaneous keypresses so you'll be able to run, jump and shoot at the same time :)

For Mac OS X users that are contemplating getting this, here is some compatibility info and other tidbits that I couldn't find anywhere else:

* There's only one Windows key (which correlates to the Apple/Command key on the Mac) and the positioning of it is a bit awkward for keyboard shortcuts on the Mac, however ...

* Remapping ALT keys to Apple/Command and the Windows key to ALT/OPTION makes it feel MUCH more natural, but leaves you with only one ALT/OPTION key on the left side. Though, the tradeoff is that you will instead have two Apple/Command keys. As mentioned, the ALT and Command keys are a bit small.

* The volume adjustment on the keyboard works great with OS X as do normal function keys (spaces, expose, etc)

* There are only 12 function keys, which means that brightness/contrast don't have keyboard shortcuts without some fiddling

* The INSERT key maps to the native HELP key in OS X as expected

* Because there's no native eject key, F12 is remapped to CD/DVD eject by default (and OPTION+F12 for a second drive), which means you'll have to find something else for Dashboard if you use that key for it

* Because it doesn't technically support OS X, you can't run the cool software that tells you how charged the battery is

* If you want on-screen notification on OS X for caps lock, you'll need to use one of the many third-party tools to do so (ie. Capster, CapSee, CAPS Warn, etc)

* Numlock works as the native CLEAR key as expected
