For me it is the money. I think I would enjoy it, doing the research, even the grant/publication game. But where I live, I probably wouldn't have money for feeding my family. The money you get kinda assumes you are still a student living in a dorm, or equivalent, unless you are lucky to work on a really well funded project or your academic institution can supply you with a wealth of teaching/other side-jobs. Compared to being employed as a developer, I just don't see it worth it.
