I have a desktop and a laptop both for work. In college, I normally use the library computers to do work. I bought a laptop as well because sometimes in my study periods, the library is sometimes full so I use my laptop. It's also nice to just work wherever you want in college or at home. It's up to you, but in my opinion it definitely makes things more convenient as I could just whip out my laptop during lunch with my friends, or use my laptop on my bed and do work etc.
