Hey. I am about to buy an original iPad Air. I always use my idevices on latest versions. There aren't much videos on youtube iPad Air 1 running on 9.1 and i was wondering is there any performance issues like lags etc. I am planning to use it for video watching and internet browsing. It will be my first tablet. Note: Can't afford air 2 now. Can iPad Air 1 users give me some advice please? Thank you.
