So I was looking at the 899 iMac in the Apple store for institution, and wow these specs are old! Admittedly, they aren't for high end users, but still they should be better. I'm curious mostly because I'm looking to get a new desktop and the 21.5 iMac is bother larger(college desk) and a little more then I'd like to spend. Any thoughts or info? Have updates followed the Mini in the past or are they unrelated?
