I'm missing my iPhone 5. i put it down on September 19 and don't remember where I put it.
 
I wouldn't undo anything. I might change something: Make the device 5.2" or 5.3" and reduce the top and bottom bezel a little bit. But that's a personal preference. My hands are only slightly above average. I do feel like handling the iPhone 5 was less of a chore, but with a case the iPhone 6 Plus isn't too bad. I held my wife's iPhone 5 the last night and it felt downright tiny. That amazing screen more than makes up for any size annoyances IMO. The longer I have it, the more I get used to it and enjoy it. Would buy again.
 
I love the 6+. I am a very large man and find the small screens of the 4 and 5's cumbersome to type on. I am 6'5" with ginormous hands. My wrists measure 9.5" in circumference. That will be a problem when the watch drops.
 
Love Love Love my 6+ and I use it one handed all the time. Tapping the home button twice now comes natural.
