While I agree, that it would be nice to see Apple make the computer you describe (or even the often dreamt of mini-tower) they have chosen not to. Given that Psystar didn't even sell 1,000 computers why would another company choose to test this out?
Apple is going to simply send their lawyers after this company and rightly so.
And since Apple has chosen not to, other companies are doing it and others are simply making their own Hackintoshes. Seems that Apple is missing out on a market here. I know I would buy said computer. I will NOT give Apple $3,000 for a tower though. I simply refuse. I will use my dual core G5 until it is no longer useful, and after that either build a Hackintosh, buy one of these clones or (gasp) go PC.
