So I sold my 1.5 year old iPad Mini 2 for a decent price since it started to feel slow and laggy and I never liked that life-less pale screen. now I've been without an iPad for over 2 weeks and I'm increasingly feeling the need for another one. I am focused on 64GB Mini 4 but might consider 64GB Air 2 too,since they can be bought fore pretty much same price. now do you think it's the wrong time to buy the Mini 4? was about Air 2? my main iPad usage will be web browsing ,reading,youtube,mail,note.
