Samsung Electronics unveiled an upgraded version of its ultra mobile personal computer in a move to boost disappointing sales.

Samsung next year aims to sell 200,000 to 300,000 units of the new Q1 Ultra model which will be available in May for around 1200 euros or dollars.

Samsung said the keyboard, battery life, wireless connectivity and size had all been improved on the second generation model.

The device had also been given a higher quality screen as well as a GPS navigation chip, a mobile TV chip and two cameras.
