Sony has unveiled three new ultrabooks within its Vaio range, each of which can be converted into tablets: the Vaio Duo 13 and Vaio Pro 13 and 11. The new devices are powered by Intel’s new fourth generation processor — Haswell — and run Windows 8.

Pricing is still to be confirmed, but all three will launch from the middle of June, starting with ‘selected countries’.

Like others in its hybrid laptop-tablet product family, the Vaio Duo 13 sports a touchscreen interface and feature a slide-out keyboard for dual tablet or laptop performance.

Sony also says the lasts for up to 18 hours, which we presume is on active standby.

The device features an 8-megapixel rear-facing camera that runs on Sony’s Exmor RS for PC technology. The company says its software lets the built-in camera serve as a scanner. Plus, the Vaio Duo 13 has a full-HD screen that taps Sony’s Bravia and Triluminos technologies, while its ClearAudio+ tech powers the sound.

The new Vaio Pro models are being pitched as ‘the world’s lightest touch-capable Ultrabook’; the Pro 11 weighs just 0.870 kg while the Pro 13 tips the scales at 1.060 kg.
