Hi all, What are the major improvements to the new iMac, besides from the obvious cosmetic improvements, the new ports and so on? I'm asking because many "old" iMacs are beginning to be put up for sale, and I'm considering to buy one of these instead of the new one - to save money, basically. The new baseline 27" iMac will be DKR14,600 (that's $2,500) here in Denmark. Meanwhile, you can get 1-2 year old used 27" iMacs (in near-perfect condition) for around DKR10-11,000 ($1,700-$1,900, and let's say that I can negotiate it down to around $1,500), also with 8 GB RAM and with an i7-processor (instead of i5 in the new baseline model). Will there be a great performance boost with the Ivy vs Sandy? And with the faster RAM? Otherwise, I'm willing to miss out on the new design - to save a thousand bucks! What do you think? /Jon EDIT: I'm gonna use it for surfing and making apps. No really heavy calculations or renderings.
