My understanding of how openSUSE deals with fonts are limited so please correct me if I'm wrong.
When I look at /etc/fonts/suse-post-user.conf, the microsoft fonts are on the top of all lists:

<family>Times New Roman</family>
<family>Thorndale AMT</family>
<family>DejaVu Serif</family>

<family>Albany AMT</family>
<family>DejaVu Sans</family>

<family>Andale Mono</family>
<family>DejaVu Sans Mono</family>

With subpixel hinting, I'm very satisfied with how current default fonts (DejaVu series) look. But as soon as I install Microsoft fonts, MS fonts are used as defaults and fonts become very ugly. I wonder why MS fonts are on the top of the list. Is there any special reason?
