For those looking at iMacs...
It's discounted at Adorama currently. The 2tb fusion has 128gb flash storage vs the 1tb fusion drive (32gb). I went to the Apple store and polled a couple reps on what they thought... 2017 or 2015? When they saw the price, they immediately recommended buying the 2015.
What seals the deal? No tax except for NY/NJ.
Looking quite nice on my desk right now.
For comparison, Apple is selling refurbished for $1439.
