Sadly, even though interface designers don't have to use the new real-estate, they still do. Even Google is guilty of this - Google Maps has interface controls at the top and bottom of the screen. This is aggravated by the fact that Maps is one of those apps people tend to use while walking (or driving), specifically when two-handed use is most inconvenient (and just plain unsafe).Folks don't care as much if Facebook or Mail takes two hands because you're far more likely to be sitting down (or at least standing still) operating them.
