I'm disappointed that aside from the iPad mini 2, the CPU is always behind.
I wouldn't mind paying $499 for an iPad mini 128GB with a more up to date CPU (even if it's the iPhone one).
That's interesting.
2012: Original iPad mini, launches with 1 year old A5
2013: iPad mini 2, launches with current A7, making it an effective iPad Air in a smaller form factor
2014: iPad mini 3, essentially added Touch ID and gold colour, keeping A7 and letting it fall behind the A8X in iPad Air 2
2015: iPad mini 4, matches the laminated display of the Air 2 and gets the 1 year old A8
Besides 2013, it's essentially always been on a 1+ year old A series SoC.
This fall will be really interesting (assuming the iPad Pros are updated) to see what happens to the mini. I think they'll either:
1) let it sit stale like they do with the iPod touch (sadly I think this is what they're going to do)
2) update it to the A9 or A10, no design change and leave it as is for another 2 years (I wouldn't mind this)
3) give it the iPad 9.7" treatment - back to the iPad mini 2 dimensions, drop the shine on the chamfered edge, A9 SoC, and maybe hit a $199/249 price point calling it just 'iPad' like the 9.7. (This would result in the cleanest lineup I think - two choices of iPad and two choices of iPad Pro. Also I think could potentially drive a lot of sales going into the holiday with a $199 iPad option).
4) discontinue the mini line entirely (could be a possibility since they really didn't give it any change when they updated the 9.7" iPad, though given how they still sell iPods that can't even access Music I don't think they'll axe it)
5) I guess if I try to cover all options - a last one would be they give it the iPad Pro treatment, and it gets the new design that the upcoming 9.7 and 12.9 inch Pros get along with all new features. Definitely a possibility. Heck maybe even a decent one given that they've positioned the mini 4 to be a premium product compared to the iPad 9.7". Hmmmm
