If you really want to have something to play with, I would suggest a cheap PC and put some kind of form of Linux on it. Then you can run WINE (which can run some windows applications), and dual boot into ChromiumOS. This kind of (sort of, but not really) gets you all 3 worlds.
All that being said, I would only do what I suggested as a hobby....not on a device primarily running for school or work. Because if all this breaks (and it WILL. Not maybe, not might, it WILL), you will be without a PC for who knows how long. As a software student, you can't afford any breakdowns. Trust me on the last sentence.
