I had a choice as some. My iPhone 6 was yesterdar arriving in the mail and in addition I had a reservartion from 10am at the Apple store for iPhone 6+. My thinking was that if I liked 6+ better, I would buy it at the store and just return the 6 that came in the mail. Price differance was minimal and it did not metter to my final choice.
Well, I got into the store and went to check both phones. I saw them, held them, looked at the res, opened the map app... I did not wait for any salesperson to serve me, just run back home so that I can avoid missing my UPS guy and getting my 6 before the weekend starts. I read similar reaction on other people's faces in the store as well.
I could not be happier with my decision. I got a new phone instead of a tablet (I already have an iPad). It's practical for everyday occasion. Battery is fine, I always carry my hootoo with me anyway. I had exhibited my photos even made with my iPhone 4, so creativity is more important then anything (I have a nice DSLR with pro lenses for sharp, micro... images if I need features such as IS)...
Now, I hold my 6 confidently, easely (I even have lond fingers), descretely if I want, screen size is perfect, nice for photo viewing, navigation, browsing internet, traveling to other places and speaking/making photos without drawing too much attention...
Will defenately chose the same size the next time.
