I just bought a new macbook pro for school next year. I really don't know what mouse i should buy. Right now i have an mx revolution for my desktop, and i love it. I like having the full sized mouse, but don't really want the dock to go along with it. So i am deciding between the vx revolution and vx nano. What are your opinions on each? I love the micro receiver, so I wont need to plug and unplug it every time, but does that drain battery life?
