Ugh. So, I need a new computer, and I've been keeping my eye on the 20 inch iMac. I noticed the Apple Store has refurbished models for a good price, however, as many of you know, the last time the iMac saw an update was in August 2007. I am desperately waiting for new iMacs to be released so I can compare the new models with the current (old) ones. If the upgrades are very minor (i.e processor, speed) then I suppose it would be OK to purchase the older refurbished models I see now. But, what can I expect in the new models? And, does it seem logical to even consider buying a year old refurbished model? Does anyone at all have a clue as to when Apple will update these? thanks for your input!
