"Happily, pen input works well, even on this pre-production unit. Like it did with the Duo 11 and Duo 13, Sony went with an N-trig active digitizer to power the pen input. While a few of our readers might be disappointed it's not a Wacom digitizer, Sony explains it chose N-trig because it places the sensor at the tip of the pen, allowing for the best possible sensitivity. Indeed, the tablet picked up all of my handwriting; I never had to go back and re-trace my penmanship. "
Vaio Duo 13-al volt szerencsém dolgozni és lehet hogy egy olyan elsz a céges notim, egy gyári programmal próbáltam, pontos volt, max. egy kicsit laggos ha nekiálltam mint a marhák firkálni.
