I've just upgraded my mini 2 for a 4, and jumped to the 128GB storage. Planning to sell my 2 and a HDX 8.9 to help towards the cost (whatever I get for them). First time I've not bought from Apple, I went to John Lewis and got it with a three year Warrenty and 3 years accidental damage for an extra £30. I was a tart as well and got the gold
Nothing I've ever had beats an iPad for ease of use. The Air is too big for me now but that's hubbys size, he will upgrade next year when hopefully they'll upgrade the Air 2.
