Well, I'm a male and my hands aren't small. But 5" is still too big for me. I mean I'm using a 5" phone now, but only because I didn't have any other options when buying. But it's damn unwieldy...
Anyway, what I wanted to say is that we already got quite a bunch of votes for sub-5", way more than needed to prove that this market is underestimated.
I also don't quite understand how things have changed so drastically... Like 5 years earlier, everyone used to say that 4.7" is HUGE and people would look at you in a weird way if they saw you with that kind of a phone. Lol, I got an HTC HD2 back in 2010, it was 4.3" and I got some weird looks at school. It was too big to be normal... Then smartphones became more mainstream, and it was... almost normal for some time. And now? Now 5" is considered small. Why? What does a big screen have to offer? OK, you might watch movies on that thing or something... but couldn't you do the same thing earlier? Why was it "huge" some years ago and "small" now? This is really weird.
Oh well, I'll just keep hoping that someone will wake up and make a normal-sized smartphone again.
