Hello, I have a time constrained question and cant find the answer on the other threads... iStore in town is offering All Macs (Imacs and Macbook Pro's incl. Retina) 10% off today only as they have been open 1 year today.... In UK top 27" iMac = £1650 with discount = £1485... 2012 top iMac will be £1699 My question. I have 4hours and 40 mins to decide if I want to buy or not so is the new 2012 iMac specs £225 better than current? I need computer savvy people who know about GPU and CPU as I knoe nowt.... My biggest fear is the "New River Phoenix Operating system works on 2012 iMac 2011 no longer supported" kind of jazz in the future.... Thanks for any responces.
