The size of the internal memory of a tablet is important, because it is here that the tablet’s operating system is stored and where at least part of any app needs to be. Yet there is also used created and downloaded content, such as photos and videos taken with the camera, or such as ebooks.
This is where a memory card slot is useful, as it allows the internal memory to be used to store the more important stuff that needs to be there. The Tagital T10K comes with a memory card slot that is capable of taking memory cards up to 32 gigabytes in size, which is pretty standard for current children’s tablets.
