I'm waivering back to getting a Mac Pro instead of a notebook. With no tax and edu discount these were my options: (1) Single Quad with 8800 gt $2329 (Wait 2-4 Weeks or (2) Dual Quad with the ATI $2599 (Get today) Upgrade to 8800 gt at a later time. I would love to just pick this thing up today and start using it since it will be my first Mac. I know its gonna cost me more to upgrade to the 8800gt later but if I order it online not only would I have to wait 2-4 weeks but i'd have to ship to a friend in a tax free state. The store is in a tax free state 20min away so I can just drive there. ARG! I was ready to wait for the Macbook Pro update but i'm concerned about the durability of a Laptop vs the Tower. Should I be concerned?
