Hey everyone. New user here. I'll keep it short. I had an old iMac G5 (before the iSight) die on me a few weeks ago. Failed logic board. Not worth replacing. It had a good life though... 4.5 years of constant use. I need a new computer for when I go away to college in the Fall. I would love another iMac. I also realize that Core 2 Duo processors have been around a while. Not that they're becoming obsolote, but it doesn't seem like they have THAT much life left in them. The thing is, I want a computer that's going to last me for 4 to 5 years in college. I would love to get an iMac with an i5 or i7 processor, but the 27 inch screen is far too cumbersome to be worthwhile. So my question is, do any of you have any ideas on when the CPU of the 21.5 inch iMacs will get an update? Mind you, I don't NEED the computer until August or so. I would prefer not to wait much after April, but I will if it is necessary. Thanks in advance!
