Ok, back in reality, even a single Xeon is too expensive for Apple to hit a sub $2K price point. They would need to build an i7 version with a whole new logic board. Apple already did that and it's called a "Mac Mini". Apple's product managers dream nightmares of an invincible xMac cannibalizing their overpriced iMac sales.
BTW I must say this tube thingie is a work of art and it's hard to believe even some fanbois are trashing its design. Just wait until you see it person - the polished dark metal strikes the perfect mix of elegance and badassery. The lines and stance suggest some dark power resides within, a power so confident it need not assert brand by putting any sort of logo in view. If this is Ive unchained from Steve Jobs's artistic micromanagement, Apple's products are about to rock at a whole new visual level.
You really are clueless with this repeated i7 nonsense. Did you note that the $800 mini uses a cpu that costs more than the one in the base mac pro option? Arguably the discrete gpu is an additional cost, but they're closer than you might think. An "i7" version would have one cpu option. It's the same one used in the top spec imac. I'm not sure whether it would improve volume discount, as I don't think that is exactly the most popular imac option. Below that you move into i5s. If you mean Sandy Bridge E i7s, they cost the same amount and kill any savings derived from the reuse of whatever parts. Where are you deriving your cost savings or your evidence that the price of these machines is tightly coupled with construction costs as opposed to broader pricing strategy? As for designs, aesthetics mean very little to me.
