If you want/need to run a very particular version of Linux software, then maybe a Chromebook's not for you. But many thousands of people successfully run all kinds of Linux software that works just fine inside the Crouton environment. I didn't and wouldn't say you're a bizarre edge case, but xbmc is being far more picky about versions than it needs to be and that's not ChromeOS's or Crouton's fault. It's unreasonable to criticize the platform because it didn't satisfy your one use case, and it certainly does nothing to refute my original point that ChromeOS isn't just for newbies.
