This is me. It fits in pockets (who cares if it sticks out?), has fantastic 2-day battery life (for my uses), doesn't feel or look absurd when making a phone call IMHO, and the big, bright screen is just amazing. Not to mention the camera is much improved (colors are true, focus is great - although this may be also true for 6) and web browsing is also improved. However, after using it since Friday, I am still having trouble achieving comfortable typing accuracy on the bigger portrait keyboard and it just really feels awkward holding it and navigating/typing, even more so in landscape mode. It is somewhat difficult/awkward to handle/ carry around and for some reason harder to know where/how to lay it down; it's not the weight, just the sheer size, I guess. Obviously my motor skill memory hasn't adjusted yet so I'm hoping handling becomes much more comfortable/natural in the next week. Anyway, I will give it a few more days. It would be hard to return, though, and give up the screen and battery life. Probably will end up keeping 6+ as its benefits outweigh trade offs for me.
I actually like the weight of it (always thought 5/5s felt a little unsubstantial) but I am worried about finding suitable cases that don't weigh it down or turn it into a massive , tacky device. It seems like there are way better and more numerous case options for the 6. And I am a person with a severe addiction for multiple case options.
