I really hope this works but the initial experience by The Register is worrying. Bluetooth peripheries suck in my environment: jumping mouse cursor and missing/lagging/repeating keystrokes. And the Mac's Bluetooth module occasionally freezes and disconnect ALL peripheries. Logi's Unifying Receiver is very nice but it has a very bad track record of security. This new toy seems to address that.
