Hey you guys/gals. I wondrous question for anybody who takes classes right now. Ive been debating on getting a MacBook for the soul purpose of college. I already own a PMG5 and a PC and I also own a Vaio laptop but its a 15.4" unit so its a little too big for class while a Macbook is much more discrete. My question is though, is it even useful? Anybody here actually take their laptop to class and get something useful out of it?
