First off...I've done a search, and was not able to get an answer to my satisfaction, got some contradicting answers. I am wondering if the v270 is a good buy. Not willing to pay $70 for mighty mouse, and v270 seems like the only other option. I will not game with it. It will be used on the go, mainly for when I am at school coding/surfing web. I am concerned with major lag. Can people help me out, tell me what they think. Also, I've read somewhere about some free drivers non-logitech which seem to help performance?
