What important things are left to improve the iMac? Retina display, all solid-state, etc... Also list when you think the update will come to the iMac. I'm in a position to get an iMac of my choice for free now or later. I don't NEED it as my 2009 MBPro is still rockin. Basically, I'm deciding if you think there is a big update coming to iMac next year, since the update this year was relatively minor IMO. If there are some serious things that people were surprised they didn't see in the update this year, perhaps I'll wait to get my iMac.
