PC-Z1 Netwalker: Available today in Japan, Sharp's PC-Z1 Netwalker micronotebook is based on an early Freescale prototype system. It weighs just 13 oz., has a 5-in. screen and can run for 10 hours on a charge. Because it runs on Linux, it won't be for everybody, but the NetWalker comes with apps for Web work, e-mail, images and keeping up with your busy schedule.
