What do you think all? I have a stock 20" iMac on it's way soon, and I wanna get a new mouse (I hate apple mice). I'm looking at either the MX900 (about £50) or the MX1000 (about £60). The MX900 is bluetooth (though I don't have BT on my iMac - stock config - I *think* the mouse base station "emmits" the BT signal?) and optical. The MX1000 is normal wireless (not BT), but is <dr evil>LASER!!!!</dr evil> So what do you think I should do?
