Hi, Am I the only one with lag issue ? It doesn't happen always, but when it does, it's very annoying. I've been trying to find out the reason, but I still don't know.. First, I thought it has something to do with batteries, but they're fine. Then I thought it's from OS X, but the trackpad works just perfectly while the magic mouse lags.. Also, tried to Reset PRAM, didn't help too much.. I think it has something to do with bluetooth, but I have no clue how to fix it. Anyone in same situation?
