The U2E is lighter than the Air, about 1.2kg versus 1.4kg, in part because of its smaller screen, about 11 inches versus 13 inches, and a tighter keyboard. The sides aren’t tapered to an edge like those on the Air, because the U2E comes with all of the standard connectors and a DVD-R drive. The square edges make it seem much thicker than the Air, although it is only a half-centimeter fatter.
The U2E costs US$1,999 now, but in a few weeks a version with a 32-gigabyte flash drive will go on sale. At US$2,699, that will be more expensive, but also 0.3kg lighter because it sheds the heavy metal of the hard disk drive.
