You get more than you got for the same price last year, so it's a good deal if you don't already have a Mini and want one.
BUT... I don't think anyone will buy one over the 2 unless they have lots of spare cash.
These devices have a short life cycle, we expect they'll drop the price about every year, so the mini2 was expected to drop in price. We also expect to get more every cycle.
Consider: what did Air buyers get:
-better screen
-thinner
-wifi
-touchid
-faster chip
-barometer...
what did mini buyers get:
-gold color option
-touchid
It's not enough that we get more for the $399, we always (almost always) get more for the same price (sometimes they up the price).
Computers devalue pretty fast, even tablets and the mini has been mishandled from the start.
Mini 1: late with a poor display
Mini 2: late (compared to Nexus) never went on sale at retailers whereas full size did.
Mini 3: everything is outdated. TouchID is not new... everything about the mini3 is OLD NEWS.
Only good news is the mini2 (if it goes on sale this XMas season) will be a good deal.
Target offered about $70 or so gift card + some $20 off retail ... ONLY on the full size, never on the mini2.
I really hope Apple will be introducing a Mini4 this spring and it'll be a FULL upgrade to at least where the Air2 is (at least).
Everyone pass on the mini3, let Apple know it's a dud.
