Nexus One? Without removing Android? Contrary to popular belief, the world will in fact not end, and in many cases, lives could very well be improved. One particular modder over at Nexus One Hacks has managed to put together a video how-to demonstrating the installation of Ubuntu as a secondary OS on his rooted N1, and while you'll obviously find yourself dealing with a few incompatibilities should you follow suit, it's not like you really have anything better to do tonight than tinker. Right? Right. Jump on past the break and mash play to get going.
