If you're just using it for AM stuff, and don't require the capability to do graphic work on it, then just get a 7" EEE with Linux.
It's smooth, it's fast, and it fits into a large coat pocket.
Perhaps most importantly, it's harder to waste time on it because it doesn't pack enough grunt to play any decent games, and you'll hurt your eyes trying to watch movies on the tiny screen.
Oh yeah, and they're cheap enough now that if it's broken, it's no biggy, so you can just waltz into a shop and buy another one while you wait for insurance / warranty shit to be sorted and keep on going.
