So I've had a first gen ipad mini for over a year. It's okay for what it does (play Candy Crush, read books, surf the web) but lately it's been crashing a lot, ever since I updated to iOS8. I checked out Best Buy and it says I can trade in the mini1 for $130. I would use that gift certificate to get the mini 2. Is this a good trade in deal or are there better ones?
