Personally I'd be fine with it if it was comparable. By that I mean 10% more leg room equates to a ~10% increase in airline ticket price. But currently business class tickets are significantly more expensive - sometimes 200%+
It's really not. I would simply like the option of having smaller size mobile phones available on the market. I don't really give a shit if they are differently priced. If they only existed that would be a huge improvement from the current situation.
