I purchased this Bluetooth keyboard to use with my Motorola Xoom (Android tablet), having read on a blog that it is indeed compatible. I have been using it for the last several days, and it is perfectly compatible.
The range is perfectly acceptable, even in my office environment with lots of wireless devices running (any of which could potentially interfere, but thus far haven't)
Normally I find "curved" keyboards tricky to adjust to (with the more traditional inline keyboard my usual weapon of choice), however this one accommodates my "sausage fingers" perfectly.
On the Android at least, it is often difficult to get both the keyboard itself, and the number pad to connect at the same time... but this is an Android issue, as the two co-connect on Windows without argument.
The ultra-slim profile is nice, though I've concluded that the only feature this keyboard lacks is the ability to raise the top (as in, a collapsible stand). If this isn't a problem for you, then I highly recommend this product to anyone with a need for a Bluetooth (or generally cordless) keyboard.
If you don't particularly require a Bluetooth/cordless keyboard, I'd suggest the Logitech G15.
