If games are of interest, then I can guarantee you that the logitech g7 is the best bet. Even if you have an inkling of playing a game, you will be furiated when the mouse stops working and you suddenly die or have screwed up motion in the game.
I use the G7 for school work and for all applications too and I find it far more accurate, easier to use for my medium-large hand (palm grip), and I paid $30.00 for it on Ebay.
I have a macbook pro 13.3" standard 2 gigs of ram and it plays team fortress 2, and counter strike source pretty well that it serves all my minimal gaming needs (no need for ps3 or xbox 360 or a gaming desktop/laptop for the matter).
I am not a gamer, but I like taking a break from work by killing some dudes as I find it also increases my concentration/focus ability afterwards too!
Seriously, don't let the downside of a usb receiver discourage you from this. Just unplug your printer or whatever unnecessary item that is hooekd up to your laptop at the moment --- I mean what do you have hooked up to your computer that you need to be on all the time?
the usb receiver has a base that can hook pu to the laptop and it has a mini receiver too (it's not micro sized but its the length of a large paper clip).
Forget bluetooth. I heavily researched/used bluetooth mice and they all sucked.
At the very least, if you're gonna go for a bluetooth mouse stay the hell away from the apple bluetooth mighty mouse --- it's a terrible mouse for the price and you can find many much better ones for a lower price AND AESTHETICALLY APPEALING TOO.
But again, go for the G7, utilize your macbook pro to its max otherwise you just ended up spending $300-400 more on a luxury Toyota Camry (Lexus ES300)
