Windows On Mac :: Virtualized Windows And Linux Performance On A MB Or MBP?

I am a high school senior. Next year I will be going to college and majoring in Computer Science. I am going to purchase a laptop for school, and I'm sure that you can all relate to the fact that there is simply no way that I am going to drop a grand or two on a Dell or Sony; a Macbook or a Macbook Pro is definitely in my future (actually, I've wanted an Apple computer for about five years now).

However, due to the nature of university computer science work, it is inevitable that I will need to run both Windows and Linux to complete research, assignments, and projects. Because I will need to use these two operating systems on a daily basis along with OS X for personal use, I have decided that virtualization, not Boot Camp, is the right option for me. I think I will use VMWare Fusion, but let me know if you think Parallels is much better.

I am trying to decide whether I need/want a Macbook or a Macbook Pro. I have weighed many factors, such as price, portability, expandability, etc., but my question is this: for day-to-day virtualization of Windows and Linux, is a Macbook Pro necessary for acceptable performance, or would a Macbook do almost as well? If Windows XP or Vista or 7 on Parallels or VMWare on a Macbook will drive me nuts with lag, a jittery cursor, etc., then a Macbook Pro would be a justified purchase.

One of the main differentiations between the Macbook and the Macbook Pro is the graphics chipset; it is important to note for this discussion that I have little interest and requirement for working with video games or 3D graphics. I might have to run a few small OpenGL programs here and there for programming exercises, but this will be rare.
