Microsoft has refreshed its tablet line-up with a new entry-level device that runs more software, but is also more expensive than its predecessor.
The Surface 3 is powered by an Intel processor, unlike the ARM-based chip in the Surface 2.
That means it uses the Windows 8 operating system, rather than the more limited Windows RT.
Experts suggest the move could help Microsoft replicate the success of its higher-specification Surface Pro 3.
The bigger tablet, which was launched 10 months ago, features a 12in (30.5cm) screen, compared with the 10.8in display of the new Surface 3.
Shipments of Surface tablets rose from 1.8 million units in the last three months of 2013 to 2.1 million units for the same period in 2014, according to research group Canalys, with the Pro 3 accounting for the bulk of demand since it went on sale.
Microsoft’s share of the tablet market has grown from 2.3% to 3.2% as a result, while Apple has seen sales of its iPad decline, although it remains the bestselling brand.
Microsoft markets the Pro 3 as “the tablet that can replace your laptop”, and is using similar language for the new model.
But it will target the Surface 3 at those on tighter budgets such as students and schools, and mobile workers who may want a lighter, smaller design.
