Which is why I'll probably drop out of the tablet market when the Air 2 becomes unusable. For me, Apple tablets are too expensive and too much of a niche product with marginal utility to warrant updating as regular as phones. For me, it's a luxury, not a necessity so when it's too painful to use (sluggish), I'll be done.
The new 2017 iPad is insanely affordable and powerful if you don't need the Pro features. There's a new iPad available for all budgets.
