Google Nexus 7
Another 7-incher to hit the scene this year is the Google Nexus 7, which sports a quad-core Qualcomm Snapdragon S4 Pro application processor running at 1.5GHz and 400MHz Adreno 320 GPU. Nexus 7 comes with 2 GB of system RAM and is available with 16 GB or 32 GB storage and is not expandable. But Nexus 7 can move files or connect to an external DisplayPort or HDMI monitors through its microUSB port, which supports the SlimPort spec. The required adapter is sold separately. Google's 7-inch IPS display pumps out an impressive 1,920-x-1,200 pixels, or 323 ppi, and is protected with Gorilla Glass. The starting price for the (as-yet Wi-Fi-only) Nexus 7 is $229 with 16GB.
