I do!
I bought my MacBook Pro with money from my part time job in 2009 (I was 16 at the time, just starting sixth form), and I got my iPad for my 18th birthday (I since sold it and used the money to buy the "new iPad")
I'm now in my first year of university.
I use my MacBook like crazy in my flat (dorm) for essays, presentations, photo editing/organising, listening to music, and organising all my files. I don't use iCloud at all for documents. I have DropBox installed, and my "university" folder is in my DropBox, so I can access all my files from anywhere on campus with my iPad (there's wifi
everywhere on campus).
I take my iPad with my every day to campus, because it's great to have lectures notes or the lecture presentation up while the lecture is been given. I can also read notices on my course page, read PDFs the lecturers distribute, emails, etc in-between lectures. It weighs pretty much nothing and takes up hardly any room in my bag so it's not a burden carrying it round (like it would be to carry round my MacBook all day, heavy thing...).
I think they're a pretty good combo
the iPad is also the best way (in my opinion) to look at photographs and show them to other people. The display is just so crisp and bright!
