This will be our first tablet and will be mainly for surfing, apps (games), and movies (in the car and traveling). Our 6yo boy will be using it plenty. Before today's announcement the budget was around $450-$500. I figured I'd just jump on a 32g wifi mini but obviously the 4 is tempting. BUT, for our usage, do we even need to pay the premium for the "new & improved"? Now, I'm really leaning towards a 64gb, refurbished, ipad 3. I imagine it will do everything and more that we want. The extra space would be great to rip tons of our sons movies to for long car rides/travel. Thoughts? Insight on specs for our needs? Thanks in advance!
