Hi guys, I sold my 24" iMac last week with the idea of getting a new iMac, and have spent time pondering 21.5" vs 27", i3 vs i5 vs i7. However, recently I have been thinking of just waiting for the 'Sandy Bridge' updates because as far as I understand, they are not too far away and will bring significant updates. My other computers are a 2008 15"MBP and a 11" MBA (christmas present before you ask!). I travel somewhat and don't mind the two laptop scenario; however, when at home, I do miss the big screen real estate. My uses are pretty basic, no hardcore rendering/manipulation/editing etc. However, I do a lot of research and like to have a lot of safari windows, PDFs, and word files open at the same time - hence the appreciation for larger screens. I would like something 'future-proof' but realise that over-kill would be a waste of money. In my shoes, what would you do?
