My iPad Air 2 does alright on battery life but that’s about all I can give it. I wish it lasted longer than it did but it still gets the job done. As far as performance goes, I’ve had very few issues there. I use Pixelmator to edit photos on a regular basis and it chugs along just fine.
Simply having it on all my iOS devices means I no longer have to remember which ones do and which ones don’t, and that’s a lot of saved energy mental and physical.
I actually don’t like the anti reflective coating. I find it shows up finger prints far more than previous models and just my opinion, but I don’t think it reduces reflections that much. That being said every other aspect of the Air 2 is for me fabulous. I’ve had every iPad there’s been and this is the best.
