Pro: 15-20% faster wifi access via wireless N over older iPad 2 /4 64 gb memory version is a big improvement...roomy Even faster yet on wireless AC if you have a wireless AC router Same Beautiful IPS screen resolution and smooth Apple UI Improved camera.... Still the very best tablet device out there.
Cons: same battery life.... Pricey..... Only 1 yr included Apple warranty They made it way too thin & lightweight...a good case is a must! Don't like the little lightning plug...
