Update: We just went hands-on with the VAIO L and it's got a pretty great touchscreen sensor -- quite responsive and accurate, even in multitouch gestures. Unfortunately, the TouchSmart-style software that Sony's packed in his woefully half-baked. Hopefully what we saw was just an early prototype of sorts, or Sony's got some serious work to before October 22. Overall the hardware is pretty Sony-ish and minimal, while the glossy display looks pretty brilliant. Pics below.
