I think the key for me will be battery life. If the bump up with the 13 mini is good enough, I'd probably pay that difference since I would plan on keeping it a long time. There may be other improvements that could sway me too, but since battery life has been one of the complaints, that's what I'd be looking at hardest.Would you get the 12 mini instead if it costs $200 less ($499 vs $699 for the 13 mini)? That's the interesting question, at least to me.
