DamnI went from a 6 Plus to a 6s last time. It took a couple of weeks to get use to the smaller size and then it felt normal. 4.7 is a good size, but I have also missed the larger screen, so going up again this time to a 7 Plus. It will probably take me a couple of weeks to get use to the larger screen again, but I know what I'm in for & can't wait.
First world problems.
I love the large screen but it's really not fun to use one handed.
Plus it always is too big for my jeans
Hmm - just played with my wife's iPhone 6S .
It's very manageable but it's tiny !
