Google's new Nexus 7 looks to build on the success of the original budget 7in tablet which managed to take a large slice oft he tablet market in 2012.

Google revealed that it sold seven million of the original Nexus 7 devices, which represents 10% of the entire amount of Android tablets sold int he last 12 months.

The main update on the second-generation comes with the screen resolution, up to a Full HD resolution of 1,900 x 1,200 pixels, double the number of pixels compared to the 2012 model. The screen size remains identical.

The Nexus 7 is also thinner (by 2mm), narrower (6mm) and lighter (by 50g) than the original, and now boasts dual stereo speakers.

The tablet will go on sale in the US next Tuesday, 30 July and will come to other markets, including the UK "in the coming weeks."

Google has not confirmed a UK price, but the 16GB Wi-Fi version of the new Nexus 7 will go on sale in the US for $229, which means it is slightly more expensive than the original tablet - which could be one less reason for people to buy it.
