Google Nexus 7
OS: Android 4.1
Nexus 7 isn't the first computing device to bear the Google name, but it has the most cores—16 in all. Google made headlines in late June when it began taking orders for the new 7-inch Android tablet device designed expressly to access content on the Google Play marketplace, the niche that Amazon's Kindle Fire has been living in. With the exception of screen size and OS, Nexus 7 surpasses Kindle fire in every meaningful way.
Built by Asus and shipping since mid-July, the Nexus 7 contains an Nvidia Tegra 3 system-on-chip with four 1.3-GHz Cortex A9 ARM cores plus a 12-core GeForce GPU with 1 GB of video memory. Its 1,280-by-800 IPS panel will give it an enormous color palette, an extremely wide viewing angle and a pixel density of 215 pixels per inch. The device is at least as technically capable as Microsoft's Surface will reportedly be, but will cost about half as much. Nexus 7 runs Android 4.1 Jelly Bean.
