Obviously theres the whole "do I don't I" thing going on with a lot of people, so I wanted to ask this one. Most people say if you want/need an iMac now, buy it now. But in this case where we are days away from the update, is it actually worth shelling out for a new iMac at all? Edit: One of the reasons I ask is because buying a fully tested (current) stable system seems good, especially as the all new iMacs may be unstable. As I understand it, they will be a Rev A, but correct me if I'm wrong!
