Super-thin, super-light laptops are one of the biggest new categories at this year's consumer electronics show.
CNET'S Dan Ackerman is there, and took a look.
"The thinnest new one that we've seen is the Acer Aspire S-5.

The Acer Aspire S-5 is expected to hit stores later this year.

And it will begin selling a Windows PC version of Kinect in a few weeks.
