I agree. MP4 is the most widely used format now, especially for mobile devices.
When you get your tablet, I would suggest you download and use MX Player
. It's like the VLC for Android. That sucker plays EVERYTHING!!!! There hasn't been a format that I've thrown at it yet, that it hasn't been able to play!--
