thread revived...
I'm looking for one too. My old MS bluetooth mouse is dying. It's actually been a pretty good product, but it's old now and acting up.
It's always done one really annoying thing that I don't want the next one to do - it loses the connection after a few minutes of inactivity, I'm guessing to save battery life. But that also means that it wakes up the computer (if it's been put to sleep), and recently it's started waking the computer up over and over.
So I want a BT mouse that never loses it's connection unless I sever the connection myself. Is the MS way the exception, or the rule?
edit: after reading threads on this forum and reviews online, I think I'm between the RadTech BT600 and the Logitech v270. The RadTech looks great, but apparently has issues playing nice with 10.4.7. Will either or both of these lose its connection to the mac if left idle for a few minutes?
