Not all fonts are freely distributable.
To say more: most fonts are *not distributable*
So, you need toi purchase a license for some fonts if someone used it in his 
document, sent this document to you and you want to prevent losses from 
layout.

I am not aware about "uglyness of X11", in this context. Please explain!

XFree86 provides rather flexible font handling mechanism via Xft [1].
Upcoming Xft2 [2] will provide more flexible mechanism for font configuration 
on X.
At a moment, font selection/layout is done in:
* Qt/KDE - for KDE apps
* Pango - GNOME2
Both of them provide good support for font selection, including non-Latin 
languages
David Turner, of FreeType project, was planning to write FT Layout library, 
which could serve all apps mentioned above (GNOME, KDE) plus 
OpenOffice/StarOffice and Mozilla/Netscape.
Than all major Linux apps can have unified layout mechanism.
So far, this library is not ready, and most apps do font handling on its own.
