Exactly. None of the desktop view editors are optimized for mobile editing, because a mobile is not a desktop. The 2010 source editor works fine, but the visual editor relies on too many elements to be useful on a small screen. That's not a bug per se; it's a design limitation. There's a mobile editor in the mobile skin. Further changes to mobile are expected for next year. A big promise of UCP was improvements to mobile editing and so far that's a bit lackng with only the Mobile editor.
