I installed Ubuntu a few years ago on a partition just out of curiosity. Then one day while it was updating itself, it crashed so hard that I could no longer dual boot - couldn't run it, or update, nothing. Basically, unless I decided to reformat the partition, I'd lost a chunk of my drive for absolutely no gain.
In my totally uneducated opinion, it's an OS designed by assholes for people with a lot of time on their hands.
