I got the 7 plus, tried to get used to it for a few months, but ended up giving it to my mother and ordering the 7.
I can't deny it's very nice to have the bigger screen, but I never got used to carrying the 7 plus around. feels weird in the pocket, it's hard to use with one hand and it doesn't replaced my iPad in any way. So I rather have a 4.7" iphone in my right pocket for easy access, and the iPad in the backpack when going to college.
I don t need the dual Camera, and 2gb of RAM is enough considering my last phone was a 5s. Still.. most people I know love the plus and find me crazy for replacing it for a normal 7, but well.. 7 has very good size.
