I am new to the forum and hope I am asking my question in the right place. I have been visiting Macrumors since 2011 and finally decided to make an account on the forums. Anyway, yesterday I picked up a 128gb iPad Air 2 at Target to replace my iPad 3 from March 2012 and I had them price match it to Staples deal of $140 off. So I got it for $559.00. Once I got it home and set it up I noticed that it is running iOS 8.1.2. When I opened the photos app it also asked me if I wanted to sign up for the beta of iCloud Photo Library. I almost had to laugh when it said beta because that was quite a while ago. It must have been sitting on their shelves for quite some time. The performance is awesome and their isn't any lag on it. What I am wondering how is the performance of iOS 9.1 on the air 2? Does it lag or is it still as fast as iOS 8? I have already started putting a bunch of my stuff on it and if I upgrade to 9.1 is it best to do it over the air or connect to iTunes to do it? I just don't want to upgrade and have lag like I do on iOS 9.1 on my iPhone 5s. I would really like to know how everybody else's performance is on the air 2 on iOS 9. Would also like to know if it is better to connect to iTunes to update since it is a full update isn't it?
