The battery lasts 4.5 hours which is disappointing even at Ultrabook standards. For a double battery boost, there's the optional extended battery pack.
With any other Ultrabook, the VAIO Duo 11 has an Intel core processor. The higher end S$2699 (US$2209) model contains the i7 core and the cheaper S$1999 (US$1636) model uses the i5 core.
With 8GB RAM, 256 GB SSD for the higher end model and 4GB RAM, 128 GB SSD for the cheaper model, the insides of the device are similar to many Ultrabooks on the market. What sets it apart is the 1920 x 1080 pixel full-HD OptiContrast panel that makes colours look crisp and vibrant. The Intel HD Graphics 4000 doesn't hurt either.
Applications wise, Sony has developed three apps unique to VAIO DUO 11. They are: ActiveClip, Note Anytime for VAIO Duo 11 and PowerPoint Add-in.
Overall, the VAIO Duo 11 is another unique design from Sony. If you're ok with the weight and possible fragility of the Surf Slide mechanism, this device is moderately adequate as a best of both worlds device. It's advisable to get a hand-on idea of the slablet before deciding to purchase the device to see if it meets your needs.
The Sony VAIO Duo 11 will be available in Singapore in November 2012
