Maybe I'm just an old fart but using the Plus has made a significant difference in my ability to consume information rapidly. I am borderline needing bi-focals so the ability to have the larger screen with the 'zoomed' interface has given me the pleasant experience I had been missing. I didn't want to make the jump to one of the Android platform large phones and rarely buy a first gen of anything anymore (so, no 6+).
When the second generation Apple Watch comes out, I will more than likely get on board with that device as well.
