Not content to let the other OEMs have all the Windows 8 tablet fun, Sony has announced a new 11” convertible ultrabook – the VAIO Duo 11 – that uses a sliding hinge to transform from a notebook into a tablet.

The Vaio Duo 11 weighs in a 2.86 pounds and measures 12.6 inches x 7.8 inches. It features an 11.6” IPS display with a resolution of 1920 x 1080 and 10 point multitouch. Also, it has stereo speakers, a 2.4 megapixel webcam, full (backlit) qwerty keyboard, and pressure sensitive digitizer. Interestingly, the Duo 11 does not have a trackpad. Instead, it has a small touch sensitive trackball that resembles the pointing sticks on IBM/Lenovo PCs but on the Vaio Duo 11 the nub does not move. In that respect, it is more like the trackpad on some Blackberry Phones, but smaller. There are two mouse buttons below the spacebar, however. Other specifications include a magnesium alloy chassis.

Sony is calling the hinge the “Surf Slider” and the display slides forward to lay the display flat over the keyboard for tablet mode. As Ars Technica points out, when the computer is in notebook mode, there is a ribbon cable to the display that is exposed which is less than ideal.

Ports around the sides of the device include a VGA video output, card reader, and headphone jack on the left, and two USB 3.0 ports, one HDMI output, and a power button on the right. Reportedly, there is also an Ethernet jack.

Fortunately, Sony did not have to compromise as much on the internal specifications to achieve the 11” form factor. The Vaio Duo 11 includes an Intel Core i3 (Ivy Bridge) processor, 4GB DDR3 RAM, and a 128 GB solid state drive.

The convertible ultrabook will come pre-loaded with Windows 8. It will also include Wi-Fi that can establish ad-hoc wireless connections with other devices by tapping the NFC radios together.

Sony’s Vaio Duo 11 will go on sale October 26, 2012. Prices will start at $1,099.99, with more expensive models adding more storage or a faster processor. It is a bit pricey, but this PC is positioned as an ultraportable convertible tablet, and in that respect it is priced competitively with the competition.
