I don't. Nobody brings a laptop to classes(unless he plans on gaming during the lecture, that happens a lot). Most of the actual work is done with pen and paper. However I would certainly miss bringing a laptop to the library, camp out for 5~6 hours and wait for the staff to chase me out.

Also, I plan on moving out sometime next year, so the weight could be a problem.

I'm not concerned with the PC atm, seeing that it's the cheaper solution. Can I actually get work done on a tablet?
