I don't think that link is correct, I couldn't access your review through it.
My wireless keyboard and mouse arrived last week. I'm surprised just how wonderful it is to be free of the wires. In a way, the iMac was really made for wireless because now I can really take advantage of the adjustable screen as I write with the keyboard on my lap and adjust my seating position to whatever feels most comfortable for the next five minutes when I have to move again.
The mouse is also very cool -- its a bit heavier than the traditional Mac mouse, but I think that's a good thing. It would be nice to have a wheel, I can do without two buttons.
By the way, the Apple website talks about sitting the mouse on your leg -- and they're not joking, it works great that way. I think this thing would work on just about any surface.
