Which has a good survey of loads and the only don't buy is Hannspree Hannspad.Top brands, in no order, are Apple, Samsung and Asus. I have long been a Sony fan, but I have recently bought the Samsung Note 10.1 with the pen. At £399 it is not cheap. I am impressed with it and have not had the chance to really investigate it's potential yet, it may even replace my laptop one day. Depending on the age of your child it has a Kids learning section of loads of things, not just how to use the tablet. The pen is handy and not just a gadget. The Samsung Tablet is cheaper but has no pen and is not so powerful. Best thing is to pop into town and play with one. In Cardiff at least Samsung have a demo stand and it's very helpful, especially as they are not selling.
