I am on T-Mobile's JOD program, and was using the 6+ for about 3 weeks when I preordered the 6s because the size was getting to me, and the one-handed use was not very easy. Of course, over the two week waiting period I got much more accustomed to the larger device. I like the smaller form factor of my 6s, but do miss the larger screen of the plus and battery life. Oh well, life goes on, and my wife was tired of hearing me contemplate size differences! I just hope they improve the ergonomics on the 7+, then I will gladly get the 7s+ in 2 years!
