So, i am ready to purchase a top of the line iMac (upgraded RAM, processor, HDD+SSD, etc.) but of course as an avid rumor reader I'm constantly waiting for refreshed products. The Buyer's Guide currently has the iMac as "Buy only if you need it", i don't urgently need it but i would like to have it by March 2012 so I'm kind of waiting for a January-February refresh... I'm kind of thinking there might be a bit of a redesign too, you know, maybe they'll ditch the Optical Drive... what do you guys think? Do you think we will se a new model early 2012? Thanks.
