There is a consensus among students that, if at all possible, you should bring a computer to campus. The labs (in dorms, the library, and some classroom buildings) get middling marks from users, who note that it can be hard to get a machine during midterms and finals. More than anything, the labs seem to be an added convenience to be used when you’ve got a few minutes in between classes. They are not, that is, adequate substitutes for a computer brought from home.
Georgetown's technology system is pretty good overall and definitely gets the job done. If you are in the business school, then you will have access to excellent technical support until 12 a.m. every night as well as free printing. The University will work with you if there is anything missing.
