Been playing around with the MacBooks regularly at work (I work at Best Buy) and I've found that they are pretty decent performance wise, but the MacBook Pro is definitely a faster machine depending on what apps you load up, and it looks alot better while doing it.
I'm going to be making my purchase for my first year at University aswell. As far as I've been told, I won't be needing a laptop inside my classes. Instead I will probably be using it while I'm in the library waiting for my next class or when I'm at home doing homework, organizing my notes, etc.
Besides, nowadays most lectures are recorded by professors and put up on a host so that students can download them, so you don't need a mic or device to record the lectures in class anymore.
I can confirm that our MacBook stock at our store is quite low, which is odd considering were gearing up for a VERY busy back to school season, and laptops sell like hotcakes; but as far as I know there's no information thats been given to our store regarding any new products from Apple.
I will probably purchase a MacBook because I'm not a power user by any length of the imagination. I have a external DVD-RW which I rarely use, but it will do the job if I ever need to burn movies from my MacBook. For surfing the web, chatting online, listening to music, and doing projects, I think the base level MacBook will be fine for most University students.
My only gripe with the MacBook is its screen and how its really tough to see clearly depending on your angle of position. Maybe its just the way they sit inside our store...
