My daughter would disagree with you in re: thinness. The newer thin iPhones are easier to pocket - women's fashion being more form fitting than men's. It's a trade-off that she and presumably lots of other people are willing to make.
I'm not saying every single phone on the planet should be the kind I want....
Now if only there were more variety in phones with small screens; now that iPhones are big, what are people with small hands supposed to buy?
That depends on a third party bothering to make a case for the device at all.
Also, i could have sworn that Galaxy Note was a hit with with ladies as they put them in handbags rather than pockets...
Not that i know much about fashion, as my wardrobe is stuffed with cargo pants.
