Gave dual booting an LTS ubuntu install alongside win7 a shot for a while. Apart from the mild irritation of having no codecs out the box and the vexing terminal, it wasnt a terrible experience. It was great for consuming media, browsing the web and word processing, but not so much for games (this was before steam) and work. I can't afford to dedicate the brain power needed to find and learn a new, non industry standard open source workflow all while keeping up with deadlines.
That said, i'm keeping an eye out for a cheap commercial tablet or convertable running ubuntu touch. It should be interesting!
