For anyone who picked up the Tablet P, you can now root the system...very easily too. Pocketables forum member RayIczr goes over the method, which requires an ADB installer and a Sony Tablet Root program. Add in some allowances for the USB debug mode and unknown program sources and you'll soon arrive at an unrooted Tablet P. More details and due praise can be found at the source below.
P.S. Anyone want to do a time jump back when the Tablet P was first introduced?
