Hi - thought this would be the best place for opinions. I have an iPad mini 2. I do love it. It is 64gb and serves well as I commute 30 min a day. It's SLIGHTLY sluggish and only abt 2 tabs stay open without refreshing (by the way - is that normal?). I have AppleCare+ so going to the store on tues for apple to look at that. My boyfriend has the Air. When I hold it - it doesn't seem heavy and things look undoubtedly better. So I considered selling my mini. But for once the more sensible side prevailed and I decided I have a good ipad - it can be looked at - let's keep it. But before the more sensible side does completely prevail (obviously it hasn't) - I'd like to know if anyone has upgraded to the air 2. - Is it noticeably faster? - screen is already great on the mini 2 - is there a difference in screen quality? - this is the most important - is the air 2 noticeably heavier than the mini or lighter than the current air? Thanks for your help.
