I'm sick of waiting for a MBP refresh, and I was told today that in i5, and i7 processors would probably only be in the high end MBPs when they come out (I don't have the cash for that! My budget is about 1200 USD) I was thinking I should just go ahead and get the plain Macbook with upgraded RAM, CPU and HD space. I'm a student that does some word processing, internet, and the occasional Photoshop/Flash/Dreamweaver. I want to run Windows 7 with parallels. I have to move around a lot. You think the current Macbooks would last me about 3 years with these needs?
