Hey all, I was about to purchase the 2.66 duo intel tower today, when I saw the new iMac was released. I'm a film student looking to the tower for muscle but also the ability to upgrade (I have a g4 imac that just won't cut it for video editing and obviously can't be upgraded). Does anyone have an idea of Apple's past upgrade trends? I can't think when the towers' chips were upgraded... I don't think it was too long ago. Any indication because of the imac news today the towers might get upgraded/changed in the near future? I don't mind buying now and the towers getting upgraded 6 months down the road, I just don't want to buy now and they get updated in a few weeks. I realize also this is all speculation, but anyone think they have a decent guess/idea? Thanks!
