Hi!
I was having trouble getting the video on the site you linked to - I tried to
upload it twice but it did not seem to go through. So, I uploaded it to an
alternate location.

Please check out the short video I made of my using the touch screen on the
laptop. As you can see it is surprisingly responsive. It is not the most
useful feature since the UI today was really designed for the keyboard and
mouse, but it certainly opens up a lot of possibilities for future
development!
Best,
Lev
