OK, so yes, it would be way easier to engineer G5 into an emac than the new imacs. And yes, it would be awesome.
But really!!!! No way. No way. That makes the imac line look pathetic all the sudden, and kills the current imac as it is still growing, and just is bad, bad timing relative to the imac, and they're already tight on chips, way tight on chips, and they just made a new computer that uses the chips they're tight on. And, WHO WOULD BUY THE IMAC?!?!?! Doesn't matter if somehow they made more money on the emac, because for apple's name, the imac can't be the flop, and the bottom of the line computer can't be the big hit. Otherwise, apple is just a dell the does a really bad job at it and is overpriced.
my vote-NOT happening. Maybe in the spring, but that's not worthy of a rumor.
