picked up a wireless mighty mouse for use with my new MBP. compared to my logitech wireless mouse that I used with my Dell, the mighty mouse seems to have a lag and is not as instantaneously responsive. Side by side, the logitech on my dell laptop is much better.

I cranked the traking speed up all the way to fast but there is still a certain amount of lag. especially when I get around buttons -- it seems as though the mouse slows down when approaching and passing over buttons. Is this designed intentionally to be this way and something I just have to get used to?
