I bought a rii Mini Wireless keyboard with Touchpad from Amazon in anticipation of getting my Pi - still several months away

. I've tested it with WinXP and Vista and while it works well initially its behavour becomes quite erratic (randomly jumping back several web pages when you aren't even touching the thing). Not sure if this is as a result of the touchpad tap events (which I can't seem to disable) or whether its a faulty device. The cursor also seems to go on a go slow after a few minutes and I have to switch the keyboard off/on to get it going again.
Is anyone using these with their Pi, and if so have you found similar problems (and hopefully solutions).
Alternatively as with the OP, is there a recommended wireless combi (ideally compact for the living room)?
Cheers
