Also from Air is worth the upgrade...
The air once you have tried air 2 is a brick like the 3/4 before it
The thinner case give you the impression (in addition to 30 gr of weight reduction) that you are holding nothing... is really impressive...
In the beginning I wasn't sure to upgrade, but now that I have I don't regret at all...
The vibration is present of course, but is not all that annoying thing that people try to describe... on some games like real racing (with max volume) the vibration give you the impression that you are driving a real car ( not like real life, but better then on air )
The screen distorting is real, but you have to press really really hard...
And for the flash is not slow at all... is definitely the best ipad yet...
Battery life for me is on par with air... Only slightly faster to charge...
I'm very pleased by the screen (it is a bit different from air, maybe a little less luminous, but better quality overall): Phil Schiller described the screen like the sensation you are touching the things... He was not lying this is the exact thing that happen
Now the cons: It doesn't have front speakers, and you can enjoy this when you have tried
Doesn't have a digitizer like note from samsung
Doesn't have Oled or a higher resolution display (these are marginal; OLED no.... you save battery and improve luminosity)
Other than this I could suggest slimmer bezel and minor weight and thickness, but these are only a marginal thing... Air 3 probably would be better
