I got one and it's the best solution for replacing a standard mouse and keyboard I've seen so far. The advantages are quite clear:
1. Small, small, small and a cool design
2. useable in the dark, because of illuminated keys
2. Bluetooth (good range, stable connection)
3. Wake-up over USB (if supported by your mainboard) and stand-by over keyboard (ideal for a htpc)
4. Media Keys for volume control, next, prev, play, pause, stop are supported
But I don't want to hide the disadvantages:
1. No cradle for charging the battery
2. Needs a reset (take battery out) once a month otherwise connection is not working well
3. No support for all special keys, like F1-F12
Best regards,
Marc
