Yeah, I guess once you get used to it, playing in windowed would work. I'm just so used to moving the mouse to the edge of the screen and not having to worry about going to far. It'd be nice if someone made a quick app (there might be one already) to lock your mouse in a certain window until you hit a certain keystroke.
Yeah, the difference really is massive. With all the love for SCII on here (and Apple users in general) I'm surprised no one has posted a video of gameplay with the new iMacs yet. Granted it's only 2 days old but there are other games posted so far.
Just a cool story regarding SCII... I went to pick it up at midnight on Monday/Tuesday and the gentlemen in front of me was asked by the Gamestop employee if he would like to reserve any games (like they always do). His response was "No thanks, I haven't bought a video game in 10 years." Made me think of all the "non-gamers" or "used-to-be-gamers" out there that have been waiting for this game, and only this game, for 14 years.
