NEC, a Japanese PC vendor has unveiled a new LaVie ultrabook–called the LaVie X–that is one of the thinnest on the market. The LaVie X measures 12.8mm thick and weighs 3.5 lbs. It will come pre-loaded with the full version of Windows 8 x64. On the outside, the LaVie X features an IPS display with a resolution of 1920×1080, a thin island-style keyboard, and a number of IO ports. Around the edges, the LaVie X has two USB 3.0 ports, an HDMI video output, and a SD card reader. Above the display is a 2MP camera for video conferencing. Interestingly, while the LaVie Y has a touchscreen, NEC decided to not include a touchscreen on the LaVie X ultrabook in order to maintain its thin form factor. Reportedly, the ultrabook will run for up to 7 hours on battery power.

Internal specifications include an Intel Core i7 3517U dual core processor running at 1.9GHz with HyperThreading support, 4GB of DDR3 RAM, and either a 128GB or 256GB solid state drive (SSD). It further has 802.11n Wi-Fi and Bluetooth 4.0 wireless radios.

While you will not be able to get this ultrabook stateside without importing it, it will be available in Japan on December 27th. The LaVie X with a 128GB SSD will cost 129,780 Yen, and the version with a 256GB SSD will cost 175,000 Yen. Not including any import fees, you are looking at approximately $1539.89 USD and $2076.41 USD respectively.
