Sony partners with Cingular to offer notebooks from its ultra-portable T-series with built-in wireless wide area network capability (WWAN).

The Sony T-Series was introduced last September. The new Sony VAIO VGN-T350P/L and VGN-T-350/L have now built-in SmartWi, that lets users switch from Wi-Fi connectivity to Cingular EDGE connectivity. The Pentium M powered Sonys feature also Bluetooth, DVD writer, 60GB HDD, 512MB RAM and a 10.6" WXGA screen with XBRITE.
The difference between the Sony VAIO VGN-T350P/L and Sony VAIO VGN-T-350/L seems only to be that the P/L has Windows XP Professional installed and the /L only the Home edition.

VAIO T-Series notebooks with a midnight blue chassis will be widely available in June starting at about $2,200. Silver and burgundy color options will be exclusively sold on SonyStyle.
