If ure talking about the new MacBook pro, the 15.4" version has a resolution of 1440 x 900 and cannot be upgraded. It costs 750$ to upgrade from 2GB to 4GB, and you cant go lower. Also, it doesnt have a full keyboard.
That's why I said that you had to pay extra, there's the 17" version... Which is expensive, but can have the resolution up to 1920x1200. The GPU indeed is indeed 8600 GT, the cheapest one comes with 128MB. And the memory? You can upgrade it your self! It's 2x1GB. Price? About 2000$ Bit more if you want more.
But okay, the real bummer for you here seems to be the lack of full size keyboard and the reolution. Sorry that I cant help you with that. The price can also get in your way... I'll go sleep now before the AA-club finds me again...
