If u r new to iPad, just wait for the Air 2. It is always good to go for the latest. If u already hv an Air, i don't think the upgrade is worth the money spent. Unless u really have to have the ALL the latest iGadgets.

I'm currently using the iPad Air 1, and I use it daily at office, site, work, home, and play; I upgraded from iPad 2 @ Feb 2014. I don't see me upgrading my Air, unless the change is significant. Then again, it is up to you to decide what u need, what is a 'significant' upgrade. Some might feel the TouchID alone warrants an upgrade.
