Hi guys, this is my first post. I am saving up to buy a new powerbook laptop. I finally got enough money, and everybody is talking about g5 powerbooks or dual core g4's. I think a dual core g4 would be even better than a first rev g5 powerbook. Anyways, could i get a little backround about the whole dual core thing, and if you think it would come out buy mid july. Thanks guys.
