I know there are a ton of threads on this- but, I finally decided I would go for a mbp instead of a macbook so I can do a complete desktop replacement while maintaining portability. I plan to run a lot of VM's and doing some heavy photoshop/video editing work on this computer. My question is, between the lower end model mbp and the higher end mbp, is the 2.16ghz to 2.33ghz jump, 128mb additional memory and 1 gb additional ram worth the extra $500? also, is the 2gb in the 2.33ghz model on a single stick or two? And it seems like macmall is out of mbp's?
