Android is a good name. With or without the marketing. People know how to pronouce and write it and the little robot is everywhere so association is strong. Even non-techies get what an android app is and know to look for the the little green robot.
I personally think Digicam would have been a better name than that childish KDE capital K crap, but that is just me.
Libre Office is pretty awful in my country, OpenOffice was/is much better. Clang does not need a good name, only projects that consumers might need to know profit from having a good name. Clang is hardly something big parts of the population need to know about.
