While I'm leaning toward the 6 why would anyone not just be patient?
Maybe if I needed a phone immediately but that's about it. I guess you could sell it but I wouldn't want to live with the 6 if I truly wanted the 6+ and the only thing holding me back was inventory related.
I cut out templates and made my mind up for the 6 the day it was announced and hav eno regrets. One of my friends already returned his Plus for a 6 and he he very happy he did it.
For those who are thinking about getting the 6 because you can't find the +, don't. The Plus is unbelievable. Believe me. The screen may be big, but once you actually own one it's just amazing.
