educational tablet suitable for children

My approach son 4 years and I bought him for Christmas LeapPad, it has therefore not tested, but I've used it in order to install applications so that the operational silk console Christmas day ... He has the leapster explore and I was able to transfer to the tablet already purchased for console applications.
Sure we say a priori that there is a lot of application, but there are mini games and then the ability to draw and take pictures and retouch when you see the price of a single child camera I think we're already a winner on this point ... I'm also very satisfied with the amazon service that has delivered us in 2 days and more that made us enjoy a discount (64 euros a tablet! ) ...
The tablet works as the console so I know my son will greatly appreciate it and I prefer that to the use of a DS or Ipad not suitable for young children ... I recommend this purchase for young children only.
