We have a Samsung Tab 2 7" 4G LTE with Verzion service. Chose a no contract plan that we start when on the road and suspend when at home. I chose the 7" because it fits in my jacket pocket. The 10 is far better for reading books, etc. With the 4G the DW checks her FaceBook, email etc, while I drive. Then at night she reads her novels. For a person whom I had to virtually brow beat to try the web, I can't pry it out of her hands. We chose the Samsung over the iPad mainly because of the SD card feature and added storage.
