So I decided to geek out last night and explore chrome OS and install it on to a really really old laptop with an IDE hard drive. Why not. Long story short. Chromium OS was ok. Chromixium the ubuntu & Chrome OS hybrid is awesome. If you have an old laptop and want to give it to someone but not deal with Windows crap, Chromixium is a great start. So easy to install. Just make sure you follow the steps on how to setup the boot from USB closely.
