I'm buying a new Mac once the iMacs come out. It will probably be one of the new iMacs, but I certainly want to be able to factor them into my decision. So I'm waiting for the announcement. Does anyone think that the smaller iMacs might be the way to go because of the heat issues, yellow screen and the general stress that the weak graphics cards might have driving the 27" iMac's screen? I've also heard about slow wi-fi for the 27" iMac. The smaller mac doesn't seem to suffer as much problems. I don't think I really need all the 27" real estate. I don't care about the cost difference between two sizes since I expect to have them for years and I've always gotten good enough value for the money from all my other Macs. I'm really in the market for a new computer due to a failing screen on a 2006 iMac, so I can't do the normal wait for two months to see what the issues are with this refresh.
