I was just discussing, with a friend, the next refresh of the iMacs and if it was worth buying one now or waiting for the next refresh. He is considering the 27" iMac. Out of all possible advantages of waiting was the display size. I believe that the 21.5" iMacs will be replaced with 24" versions. I say this because the 21" screens are quite small by today standards and the prices of the 24" screens have come way down. Besides the 21" iMacs have been around for many years now; time to get up to spec. That brought up another question, will the 27" iMacs move up to 30" or 32"? If so, that would be a big advantage of waiting. I don't see them going to 32", but I could see them potentially going to 30". What's do you guys think? Is it worth waiting for to see what they do? If they leave the 27" alone (screen only), and up the 21" to 24" then the difference between low end and high end is blurred quite a bit. A 24", if priced the same as the current 21" would be sweet. Thoughts?
