Samsung has unveiled it's Samsung Ativ tablet, which can switch between the Windows 8 and Android operating systems. This news comes just over a fort***ht after Asus unveiled its own laptop-tablet hybrid which also runs both Windows and Android.

The Ativ Q has a 13.3in (33.8cm) screen that sits over a keyboard that can be folded out for typing or set to act as a stand. The Ativ Q runs off Intel's new Haswell chip and Samsung have said it offers up to nine hours of battery life.

One analyst said he expected this to be a trend that other firms would follow. "It's a very cost-effective way for manufacturers to offer extra value to consumers at a time when it's very hard to differentiate benefits from one device to another," said Chris Green, principal technology analyst at Davies Murphy Group. "You can tap into the industry-standard Windows productivity solutions - from Office to third-party programs - as well as all the mobile apps of Google's system. It's the logical next step."
