Side by side on your PC, happily... Well, you get the idea. Lifehacker points to a neat new beta installer for Ubuntu that will drop a little Ubuntu love on your XP box (Vista not supported yet), without the need for a brand-new partition. It's kinda like a liveCD without the CD. Get it? Pretty neat if you just wanna be an Ubuntu voyeur. It's still pretty beta-fied, so YMMV (and you have been warned).
