I need a tablet computer for my developmentally disabled daughter. She's 11, so it has to be something fairly durable, preferably a screen made of Gorilla Glass. She's not disabled to the point where its going to be thrown or anything like that, but she does have some coordination issues, and tends to drop things. Does anyone have any suggestions? Trying to avoid the iPad just because of the cost, but if it comes to that being the most recommended with positive comments, then so be it.
