Ask HN: Hardware Platform for a Learning Device

Hi HN,

I have a project in my head for a device that's supposed to help young children learn (~2 years).

It needs a medium sized touch screen (large enough for children), speakers and must be rugged enough to survive rougher interactions with children. In addition to displaying simple graphics, I'd like to run Text-To-Speech directly on the device. WIFI is not required.

Do you have suggestions for feasible devices with reasonable prices? I'm open for everything, Android tablets, iPads, Industrial panel PCs, Raspberry PI stuff, chinese aliexpress devices etc.

What would you do?
