I saw somewhere that Apple may discontinue the entry level imac, presumably the bare bones 21.5" model. Anyone have thoughts on what the cheapest 2012 21.5" might cost? I work in a primarily PC institution, but I've always had a mac desktop at work, and I have a chance to replace my aging system with a new imac depending on the cost. I'd like to wait a few weeks and see if the new ones come out.... The current entry level imac is about $1149 (educational discount), with the next model set at $1499. Would that become the base model? Has Apple ever hiked its basic system $$$ that much? Any thoughts, much appreciated.
