I was agonizing over whether to wait for a standard video upgrade in the Mac Mini, but the more I read about the XBox 360, the more I realize that within a year, I won't be using a Mac for gaming anyway.
On that basis, I'm just going to go pick up a Mac Mini next week, because it will do everything I need from a computer, and the 32 meg of VRam is a non-issue for my web surfing and email.
The Mac as a web tool, music platform, and to keep my things organized. The XBox as a game machine. Not a bad combination. Man, I love competition...
