Hmm... many people nowadays think "OSX Lion Calendar" when they hear 
"skeuomorphic design" or "skeuomorph interface", and I don't think many 
people within KDE like that. Marco Martin even wrote a blog post pretty 
much bashing it (I'd like to insert the link, but I can't reach his blog 
atm).
Maybe we should leave the word out and leave it at "natural design" and 
"appropriate metaphor".
