The Tab and the concept is a great thing. Unfortunately, the memory is so limited - stay away from the 8 GB even less than 4 GB left that you can re-install a few programs from Android. An SD card can not be solved, because Google only allows the storage of data, but not programs on SD card with the latest version of Android the problem. Unfortunately, there is no option to buy directly with more memory, only the Galaxy Tab S has 16 or 32GB for double the price at the Kids mode. Sad that with something like learning computer as a business is trying to make.
