Mobile computing users in Japan just reduced their Duracell budget: Toshiba updated the Dynabook notebook line and one model is rated for 13.5 hours of battery life! The Dynabook S30 is the judicious juicer thanks to the 4200 RPM drive and miser-like Intel Core Solo U1300 CPU running at 1.06 GHz. You’ll only get 30 GB of storage and 512 MB of RAM for $2,300, but battery life is a premium these days. The 1.39 Kg Dynabook S30 offers a 12.1-inch WXGA LCD for hours of viewing pleasure in 1280 x 800 resolution, runs Windows XP and is Vista Capable. Additional ports and features include 802.11a/b/g, Gigabit Ethernet, three USB ports, a PC Card slot and integrated fingerprint reader.

I’m still not sure the lightweight, fully featured notebook is worth over two-g’s, but I might change my tune if I knew I could run around the town for 13.5 hours on a single charge. Last I checked, Dynamism carried the Dynabook line if you want to test that battery claim.
