Apple yesterday updated the iPad line, with a new processor, improved camera and an even thinner body for the iPad Air, and Touch ID added to both the iPad Air and the iPad mini. But the iPad mini 3 sees only the addition of Touch ID; everything else is exactly the same as the iPad mini 2.
Nevertheless, this new iPad mini costs $100 more than the iPad mini 2, which Apple is still selling, for the base 16 GB model. It’s hard to compare other versions, as the iPad mini 2 is only available in 16 or 32 GB, and the iPad mini 3 in 16, 64 and 128 GB.

Nevertheless, that’s $100 for Touch ID, and for an iPad whose processor is already a year old, and which will have a shorter lifespan in terms of OS upgradability than, say, the iPad Air 2, which has a newer processor.
This seems like a ripoff. With Apple still selling the older model – and even the first iPad mini – it’s obvious that, unless you really need the storage, you’re better off getting last year’s model. You can even get a 32 GB iPad mini 2 for less than a 16 GB iPad mini 3. Touch ID is nice, but it’s not that big a deal, and not worth paying $100 for.
