I'm looking for a wireless mouse for my newly purchased MacBook Pro. As much as I love its trackpad, it still doesn't offer the precision of a mouse. I've always been a strong supporter of wired mice because of their fast response times, but wirelessness seems like a necessity when I'm on the go with my MBP. However, I can't stand any bit of input lag from a mouse. I don't want it to feel like a Wii remote. Is there a wireless mouse that has a very fast response time? I don't want a Magic Mouse, if any of you are thinking of that.
