Obviously a lot of you guys are not in college. My school cost me about 20K a year for classes. That's about about 1300 dollars per class, and for each class i pay around 90 bucks a book. If i could swap out even a hand full of books for a tablet, i would do so in a heart beat. No student actually reads all of their text books, but sometimes its nice to be able to look at something in class.
The tablet doesn't have to be powerful, your not going to be doing cad on it, or running 3D simulations. Its just there for note taking and looking up stuff. If someone steals your backpack or you forget your notebook, your notes and books are gone anyways.
I personally have a T61 Thinkpad, and i love it. Its not the fastest, or the biggest, but it gets the job done. I prefer the smaller screen size, mine is 14in, its more compact and is easier to travel with.
So to take out a school loan for 20K or 22K is really all the same in the end, not only that but i get to pay off that laptop over a longer period of time. I think more schools should do this kind of thing, should they be macbooks, who knows, but i would be more than happy running OSX and Windows 7 through bootcamp.
