Best Buy has iPad mini 4 128GB for $300, it's the lowest I've seen. I'm looking for a spare iPad to go along with my pro. Choices are down to ipad 2017 and this mini 4. Both are same prices. I'm leaning toward the mini 4 due to better screen and the more compact size since I already have a 9.7" Pro. But the A8 processor and the fact it's been out on market for two years now ready have me paused. Which one would you pick?
