Let the hive mind of Engadget get that for you.
"I'm looking for a wireless trackpad to use with my older (2.5 or so years old) C2D MacBook that's perpetually docked to my home theater. Something sleek, thin, not too small, made of high quality materials. Ideally, it would natively support all of (Snow) Leopard's multitouch inputs, and even more ideally, it would have a charging dock / base. The only problem is that I'm not sure that such a thing even exists. Think you can throw me a bone?"
I was most excited about the rest pad for the keyboard, but it's absolute garbage quality compared to the keyboard. It also doesn't stay attached to the keyboard, it's just lays over top of it. The rest pad is also very light, and it flexes quite a bit.
The USB connecton on the keyboard isn't used for the keyboard itself, just for the USB hubs. If you don't have a PS/2 Port, You'll need to take up 2 USB connections for the keyboard. One for PS/2 to USB conversion and another for the USB Hub.
The windows flag button is on the right side of the keyboard, and on the left is the more useless macro key button for the media keys on the F Keys.
some pros:
The Numlock/scorll lock/caps lock light is a bright LED. Very very bright and nice.
The keyboard is very nice quality, I use it for a work keyboard, not gaming.
Pressing halfway down is a nice feature, pretty responsive.
