As someone who teaches a lot of Uni classes -- let me tell you right off the bat don't even think about an iPad as your only device. If you get one, great, you can use it in conjunction with your MBA, but you can not print from the iPad, it's much harder to type on, students in my classes can't keep up with taking notes without a real keyboard...but most importantly, you will have to be able to print assignments to hand them in. You can not print from an iPad. I think Jobs said something about print being added in the next software update, but even that won't work universally. Don't get an iPad thinking it can be your only device. If you can only get one, get the MBA or a Macbook Pro.
