Re: Which tablet for my kids??
I personally didn't like the 7" Galaxy Tab 2.0 The battery life was horrible. Ended up returning it not to mention the very cheap quality pixel density. The graphics were just not all there.
Although I do hear that the Nexus 7" does really well; close to iPad's battery life which is very impressive. I'd probably go with the Nexus out of those options for the price range.
