Hello! My question is simple. Recently I've received iPad Air (first gen) with 128 GB of storage from my family member. iPad runs OK, have lots of storage capacity, but an old processor and 1 GB RAM makes me a little worried about how long it will run "good". I have an opportunity to swap for unused (box wrapped and stuff) iPad Mini 4, but with 16 GB of storage. Should I do it or should I keep my Air?
