Let me start this off my saying I just finished my freshman year in college.
In my opinion, the Macbook is the ideal student computer. It's a great machine that suits almost everyone's needs. Perfect size for carrying to class, tons of power, and great features. I have a 12'' iBook that I use take to class for notes and stuff.
However, I'm getting a Macbook Pro this summer. I'm a film major and next semester I'm going to be starting my real film classes so I'll need it for final cut. Plus I'm taking a photography class, so it will be nice.
The only students that need a Macbook Pro are students who really need the extra power and graphics. For example, film, graphic design, comp sci, architecture (for CAD), etc.
For most students, the regular Macbook is perfect.
I wish my school had their laptop program with Apple instead of Dell. Most kids just end up buying the recommended D620 which is a horrible piece of ****. I wish the school had a deal with Apple so they could all get Macbooks.
Oh, and as for the "students only need a pencil and notebook," my college requires ALL students to have a laptop computer.
Heck, walking across campus with a backpack full of books is beyond torture for them -- which is why you see those stupid backpacks with wheels.
Nobody ****ing uses those.
