Sony boosts VAIO notebook speeds for Vista

Sony this morning launched a sweeping series of performance upgrades in Japan for its VAIO notebooks in preparation for the increased demands of Windows Vista. All three of the company's ultraportable systems -- the 12-inch VAIO G (pictured), 11-inch TX-series, and the hard disk-based UX-series MPC -- can now use the faster, 1.33GHz ultra-low voltage Core Solo as an option to improve speed without a tangible impact on battery life. Storage has also been increased on the G and TX lines to 100GB.

The company also upgraded its C-series in the southeast Asian country with the option of a GeForce Go 7400 graphics chip, which helps the 13.3-inch widescreen better accelerate video in Windows Vista Home Premium. Most models will be available January 30th, though Sony says the G series will ship slightly later in the first half of February. North American revisions are expected soon.
