Rooting is definately a must to turn on the full power of this Andriod Tablet! I have rooted mine with Froyo using Autonooter and it was very easy.
Just a couple of the apps that:
Full access to the offical market
every version of Angry Birds plays really well
All of the instructions are availabe if you look up xda developers website.
I have turned twenty of my friends towards this pad. They all love it after it has been rooted.
