Tablets come in all shapes and sizes. There are tablets smaller than 7 inches but also greater than 12 inches. It is good to determine for which you want to use the tablet. If you would like to bring this often in the OV you might want to prefer a smaller tablet than if you are going to use this only at home on the couch. Also, note the storage memory. For example, if you want to store a lot of music on your tablet, you have more memory than when you put it only used to surf.
