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!
