I ended up buying the non-Bluetooth version for $99. I didn't much like the mouse, however, an am using an older Logitech wireless mouse + the wireless keyboard. They don't interfere with each other, which is good.
Physically, the keyboard is quite large--10.5" is a little wider than my homemade keyboard shelf. The keys have an excellent click to them. The faux leather wrist rest is a nice touch.
Overall I'm pretty happy, but I will have to look for a better keyboarding tray solution. I'm using a $250 Kensington artciulating arm at work, which has been excellent.
