I suppose it's ok to have if you're gonna dual-boot. I had it installed on an external hard drive but then had Grub on my main drive so I could access it when I wanted to without wasting space on the laptop HDD. Couldn't really cram it in with Vista and XP already on there.
But if you don't want to go all out, just get Cygwin-X and Putty if your uni department lets you remote access the computers. I had Ubuntu installed, but rarely used it because I just did all my work remotely on the School's Linux comps in Windows
