Okay, so I want a new Mac for High School next year, and am wondering if there are going to be any substantial upgrades in the coming months. Should I wait until Leopard (comes out 6 months after school starts, kind of a long time) because there will be a lot of upgrades? Or just wait until Merom (supposively August)? Or.... should I not wait at all and purchase now...? Please help.... all help is appreciated.
