I upgraded my duo 11 t windows 8.1. As you may notice Metamoji Note Anytime for Vaio has disappeared. For me was the best software of the tablet. Is there a chance to recovered from the hidden partition for example. The best part was when the button in the pen was a selection for the notebook. I saw the application on the windows market but I don't know how to configurate the buttons of the pen to do the sane things than in windows 8. Thank you very much.
