You sound like a good kid. Maybe a bit uptight but that's ok...
A bit uptight? I'll say. He's a college kid and can't find a good use for an iPad? Maybe he needs the full-sized Air for all the porn he isn't watching. Or how about any TV show or movie on Netflix, etc? Seriously?
I have an rMini, and if I had one in college, I would have been using it non-stop. In fact, I suggest the OP research and compose his senior thesis only using his rMini. Maybe then he'll see how useful it can be.
As an average someone, working in a corporation, earning a paycheck, and raising a kid, I draw with my rMini, compose music, read, take notes, show photos, take photos/videos, watch movies/TV shows, read the web, post comments to threads

and anything else I can do with a computer when I'm not in front of one. For me, it is the perfect solution to portable computing where the laptop is too cumbersome and the phone is too small.
However, I will concede that when my wife was pursuing an advanced degree 2 years ago, I bought her a MacBook Air 11" rather than an iPad. For working with collaborators, researching, and writing papers, it seemed like a better solution. But from a weight and usability perspective, with a keyboard, enough storage, and cloud-based apps, the iPad could have been a serious contender, especially given the better screen resolution.
