I was going to buy my 4 yr old a Nexus 7, but my wife is having a fit because he is just 4 and really doesn't need it. While she is technically right, he uses our old iphones w/o the sim card, I want to get him a tablet. Trying to figure out if getting this for $99 is worth it. I really like the Nexus 7 @ $199, but this sparked my interest as one of the cheap tablets that might work.
