Ubuntu is a desktop OS that fails on a mobile device. Don't even try.
If you are interested though, ubuntu is easy to install on your desktop. Just be warned there are barely any programs/games. Ubuntu is best for people like me who like to code, listen to music, watch movies, and use office. All for free and without having to deal with windows, the fat man who goes to an all you can eat buffet and eats even if he is full, and worse yet, still wants to eat when the food is all gone.
If you're on top of the dung heap you're still on the dung. Only difference is you crawled all the way up.
