You've made better experiences than I did, then... On each and every system I 
had the pleasure to work on so far (no, not all configured by myself...), 
Windows beat X in terms of subjective responsiveness. It just *feels* quicker 
to me. It's nothing to get really excited about.

OK, "native" was a bad choice of words. Let's just put this in the "bad 
hardware vendor support" corner...

 - One word: -adobe-courier-medium-r-*-*-12-*-*-*-*-*-*-15
 - QT seems to have some serious issues (google for "kde konsole fonts").
 - Mozilla looks like something unspeakable unless you get it running with 
FreeType. And then there's a lot of guesswork to do with the min, max and 
gain settings until it's looking good. At least it looks better than anything 
else I've seen so far.

There is no central font management. For some time now, X seems to support 
truetype fonts and antialiasing, but for some strange reason nobody either 
knows how or wants to use it.

But for efficiency reasons, the clipped content of windows isn't transmitted 
so that's not so easy.

(Disclaimer: I'd never have thought I would write such stuff some day. I've 
been using Linux/X for several years now and it has replaced my Windows 
installation for productivity purposes, but as it is now, I would *not* 
recommend it to a "standard user".)
