I'm looking at buying an iMac and have been waiting for about a year. First for Leopard and now for some better graphics and maybe a Penryn update. I have looked at the buyer's guide for the iMac and MWSF would generally place the iMac at the end of its update cycle, but many people in the MacWorld 2008 Predictions thread seem much more interested in everything else Apple may update or release. From what I'm able to tell it doesn't appear that Apple like to stack the updates too close together. It looks like apple has a recurring autumn update after their back to school promotion ends in order to clean out inventory. So if Apple doesn't do a refresh for the iMac at MWSF then when would any of you think the next update would be? Do you think the mobile Penryns will be released to apple in time to refresh the iMac for MWSF? By the way, when I eventually get this system I suppose you'd be able to label me a switcher.
