People are lining up here at Ceatec 2011 outside of Tokyo to check out the Regza AT700, which runs on Android 3.2, is 7.7mm (0.3 inches) thick, and weighs 558 grams (1.23 pounds).
Toshiba also announced a 7-inch version, the AT3S0, at 12.1mm thick and weighing 379 grams (0.83 pound).
The AT700 seems very similar to Toshiba's AT200 introduced last month at the IFA trade show in Berlin.
Indeed, it also has a 1.2 GHz dual-core TI OMAP 4430 processor, 1GB of RAM, and 32GB of internal memory. Sensors include a digital compass, accelerometer, gyroscope, and GPS.
It also has a 5-megapixel rear-facing camera and a 2-megapixel camera in front.
Aimed at the Japanese market, the AT700 and AT3S0 are designed to link to Regza TVs and Blu-ray players via a Wi-Fi router.
Toshiba is marketing the tablets as convenient for watching streaming video when you're in a room without a TV.
The 7-inch AT3S0 felt extremely light for its size and has a comfy textured back. Both tablets will launch in mid-December in Japan. Prices haven't been released yet.
