My nephew is turning six in a week and I still haven't gotten his gift for his birthday. I'm trying to decide between an HP touchpad or a Kindle fire. Since I don't own either, I'm not sure what would be the better choice..or if there's a better option. I'm trying to get him off the TV and start learning more. I feel that something like this where he can play educational games is a better alternative. I'm trying to stay under $400 after buying the device, case, accessories, etc. Any opinions?
