We have the kids version. The 8GB is somewhat useless. 5GB is taken up by the OS and FreeTime. I've read that if you take off the FreeTime you get some space back. DD1 received hers for her birthday in July and has gone crazy taking pics and videos which ate up space immediately, which then disables the wifi. So you have to delete content in order to get wifi back. I believe the model out now for $85 has the expandable memory with mini SD card. DD1's does not have that.
That said, she uses it often and it works great other than the memory limitation. The case is decent and I like the 2yr worry free replacement. So, even though it's not perfect by any means, we just bought DD2 (6) one for her birthday in 2 weeks. For their ages (8 and 6) I like that the set up for FreeTime means they spend most of their time reading books or playing educational games. I don't want them to just be able to freely explore the internet or youtube. I don't expect these to be the tablets they use for years and years, but for the $85 cost I think it's totally fine and will get a few years out of them.
