Hi, I want to buy a new mouse for my iMac which I will use for gaming and for some tasks that the mighty mouse doesn't handle very well for me. Other than those I will use my Mighty mouse. Logitech MX620 Logitech VX revolution I narrowed my search down to two options, please don't come up with other options since I've seen them all and these suit my needs the best. They both are more or less the same price, so that's not the point. The 620 looks nicer to me, but that's solely based at the looks. Main question is: Which is better/ handles better/ feels better?? Opinions and experiences would be very helpful. Thank you so much for the help!
