Hello, So after thoughtful consideration, I finally bit the bullet and went for it! That is, I made the switch: 24" iMac. 2.16 Ghz, 2 GB ram, 7600 GT. I wasted a lot of time waiting, but I didn't know any better! It's supposed to deliver any time between the 22nd and hte 26th...time to wait! Thank you all for your comments/help!!!!
