CNET gives its thoughts on the Libretto U100-S213 notebook from Toshiba. Here's a short snippet from their review:

The Toshiba Libretto U100 is built for road warriors and gadget hounds who feel that even four or five pounds of computer gear is just too much to carry between airport gates or meeting rooms. Though it's been continuously sold in Japan, the U100 is the first Libretto in six years to be sold in the United States--and it's among the smallest and lightest notebooks available anywhere.
