Well, I just got a new iMac G5 iSight and I absolutely love it (
www.apple.com/imac). However, I felt that I couldn't fully use the beast hidden under this incredibly thin box and behind the absolutely gorgeous screen with my current uses. (I opened every application I had and still had memory to spare.) So, I decided to see what games were available. I found this site and came off quite impressed.

Yes, I know it is a bit behind, but for a computer that is used mostly for business (schoolwork in this household, it isn't that bad. I like to call it an iPod on steroids.
