Sony takes on the Surface Pro with the VAIO Tap 11, its first Windows 8 tablet (hands-on) Quick take: 1. It's N-Trig. 2. Worse, it sound like it's DuoSense 1, same as VAIO Duo 11. Seems like DuoSense 2 eats more battery than 1 (makes sense since the biggest improvement is probably twice the X/Y coordinate report rate), so smaller tablets will still come with DuoSense 1 for N-Trig licensees.
