At least UCSF, I don't think that you need a laptop. You are required to have a computer that meets certain requirements, but laptops are not required. Having said that, most people have laptops. They are just more convenient. UCSF has wireless access in the library, in some of the classrooms, and other areas around campus. No one really brings their laptop into class to take notes (except for Neonam, sometimes🙂 ). The majority of the information that we receive is online (through emails, websites...etc), so having computer and internet access is pretty important. UCSF has computer labs in the library and the pharmacy school has a computer lab just for students, so you could get away with not having a computer.
UCSF also allows one to increase the amount of Unsub Stafford loans to cover the cost of a computer/printer...etc up to $3000.
