iPad 3 was an excellent iPad with the exception of the underpowered A5. It aged at a much faster pace than normal. Even the App Store now lags. With AnandTech's review how the memory footprint takes up 20 to 30% more for 64-bit architecture, does this mean that the Air will be "underpowered" in terms of RAM? I don't mean NOW but later after a few iOS releases. Remember the iPad 3 was fluid for the most part when it was first released but quickly became underpowered with each iOS. This won't affect my decision in buying an Air but it does affect which model I buy. In other words, I'm thinking of getting a 16GB model as a "loaner" so I can get the most resale value for the iPad Air 2. But if this will be sufficiently powerful, I might get the 32GB version and just keep this for years to come.
