Oh?
I humbly disagree. Or were you actually part of the designers of it? Micro$oft might have the majority believe in that, but I don't quite see it. I may be wrong, sure, but I'd prefer OpenGL any time.
What is there not to like about?
Hmm, I wonder if I can find a certain, old'ish article.
Oh yes, here it is. Something you (and maybe others) might or might not find an interesting read:

And yes, I'm a Linux user, and I certainly do not miss windoze. :]
