Google built the Cr-48 with hacking in mind, so it's no surprise that we're seeing other operating systems crop up. Still, it's fun to watch, and enterprising hackers have got most of the usual suspects up and running: first Ubuntu , and now Mac OS X and Windows. It sounds like a lot of work, and we pledged that 2011 was going to be the year we sat on our asses and didn't do anything hard, but you're welcome to give it a shot! Just hit up those source links below for instructions, and follow after the break for video of OS X in action.[Thanks Damian W.]
