The graphics card only starts out at 64MB. It can grow beyond that if the need arises to 224MB (and, no, it is not only Windows that can do it, it works under Tiger as well).'ll be buying a new Mac sometime after Leopard comes out. I'd love to get a MacBook, but the integrated intel graphics with on 64MB seems way too paltry.
It's a big jump between the two or else I'd get a MBP myself.Seriously.
If graphics are that important to you, get the Pro.
On an investment like a portable computer, get a really good one.
Spend more, worry less.
