I'm also considering a 7+ and I also have a 6s now (combined with an iPad mini).
Main reasons would be battery, bigger screen and better photo's.
Which are the good reasons, if I read correctly, to upgrade to a plus.
I wear normal to skinny pants, so I'm going to check in the apple store and put the 7+ in my pocket. 😀
70% of my time is work/home/some school/city so that would be ok I guess. Sports with a + will definitely be something new.
regarding the Steve Jobs comment: Usage of smartphones has changed a lot. Smartphones were mostly phones back that then.
Also, I'm tired that the iPad mini is treated as an afterthought. I use my iPhone all day and when I come home I want to put it aside and use my iPad mini. But the processor is at least a generation behind (still capable but the difference is noticeable ) & the hardware design is older (lock screen on the top, very annoying).
