I'm looking for a tablet that would let me watch at least 3 movies without needing to be recharged. I'm looking to watch *.mkv files (720p and 1080p) without any stuttering, and 10-11" if possible. I travel sometimes and I need something portable that will let me entertain myself without worrying about the battery dying too quickly.
I'm open to windows and android tablets. I'm looking to spend as little as possible as long as my only requirement is met.
