Oh, yeah, and besides having to learn Billspeak, the concept of having yet another useless intermediate dialog to wade through (and translate, no doubt) to get to the good ol' display settings dialog sure improves my User Experience, don't it?
And what did our buddy translate the Display applet in the Control Panel to in further improving my User Experience there?
