Google has launched it first 10-inch tablet. The Google Nexus 10 is built by Samsung. The Google Nexus 10 is built around a 10.1-inch 2560 x 1600 display giving it a 300ppi "retina" pixel density. Inside is the next generation dual core ARM Cortex A15 processor clocked at a blazing 1.7 GHz. To power the high resolution display you have the new Mali-T604 graphics and 2 GB of RAM to hold large textures. Only a WiFi version is being offered right now.
Two models are available, a 16 GB model at US$399 and the 32 GB model is selling for US$499.
The Nexus 10 is just 8.9 mm thick, but at 1.3 pounds in weight, it is really best used, as Google says a "perfect couch or coffee table companion." In those situations, I would just pull out my MacBook Air.
For a tablet, the Google Nexus 7 or Apple iPad mini are much more interesting to me.
