When purchasing a Vaio T on Sony’s Japanese online shopping website, you can choose 4 new colours for your baby. The new T also gets a digital TV tuner (the service will be available here in April), and it will be the first PC to offer this optional functionality!
Other than that you get a Pentium M773, a 80Gb HDD (or 60 or 40, depending on the model) and an Intel 915GMS video card. This model also has a 11″ screen with a resolution of 1366×768, Wireless LAN in all a/b/g flavours and Bluetooth 2.0+EDR… all neatly packed in a 1.25kg machine. So nothing really super-new aside from the colours and the TV tuner (that might not work outside of Japan).

On one of the pictures below you can see the antenna for the TV.
