I do, thats one of the reasons i am sticking with my 5s.
The other reason is that the 6/6s just doesn't feel like a premium product, it feels more like an iPhone rip off. It looks and feels a bit cheap, not avery nice phone at all and not very desirable. I am not going to pay £539 for a 16gb phone that doesn't even look or feel top end quality, whereas the 5s just oozes quality with its glass and stainless steel construction, its still a beautiful phone and feels modern even though it is in its third year of production, and still pretty quick in use, never feels under powered.
I am hoping the 7 is a lot nicer to look at and has more of a premium build quality than the 6/6s. It's not all about power and gimmicky features, us non power users just want a nice phone.
