When talking about "what consumers want", the opinions of the people in your office really shouldn't indicate that much. Especially not if they just started using their big phones two weeks ago, and still need to get used to different usage patterns after using small iPhones for (I presume) a long time. Nobody disputes that larger phones are used differently than smaller phones (large phones have advantages and disadvantages), but "different" does not necessarily mean "worse". Although that's what people often think.
You can just easily argue the other way - recently I've switched from N5 (5") to Z3C (4.6" hovewer with small bezels) and I couldn't be happier. In fact, I would happily go under 4" if there was a flagship so small.
Again, I didn't say larger phones are better. If you tried a larger phone for a while and didn't like it, good for you. What I'm pointing out is that you cannot honestly say "I don't like large phones" without actually using them for a while. I'm also pointing out that personal anecdotes don't have any value in discussions about what the market really wants.
