(Telecompaper) Google has announced a new version of the Nexus 7 tablet, the first to run Android 4.3, as well as a new device to display mobile content on the TV screen. The new tablet, developed with Asus, features a more high resolution screen, lighter design and longer battery. It also adds stereo speakers and virtual surround sound and will be the first device to feature Google Play Games, the new storefront for games on the Android app store. Android 4.3 adds the ability to set different profiles on a device, including parental controls to limit children's access to certain apps. In addition, it comes with Bluetooth Smart, to support apps that connect to new devices like fitness sensors. The new OS is already rolling out to all Nexus devices, and the Nexus 7 will be available from 30 July in the US, for USD 229. Google's other new device, Chromecast is available already for USD 35 on Google Play, Amazon and BestBuy.com. The small device plugs into a TV to allow the user to "cast" content from a phone, laptop or tablet to the TV screen. It works with the Chrome browser as well as dedicated apps, and allows the user to pause and play and control the volume of what's on TV from the mobile device. Chromecast apps are available already for Netflix, YouTube, Google Play Movies & TV, and Google Play Music, and more apps like Pandora are coming soon. Goolge released a preview on its developers blog of Google Cast, the technology behind the Chromecast apps.
