System Requirements

Mac computer with Bluetooth wireless technology
Mac OS X v10.4.10 or later
Keyboard software update
Existing keyboard and mouse for initial setup
Three AA batteries (included)

It requires Mac OSX, keyboard software, and you have to have a keyboard and mouse to get it set up in the first place? That pretty much screams "Doesnt use HID" to me. Otherwise it would 'Just Work', and work with any computer with bluetooth as well as innumerable smart phones...
