And the reality of things breaking from time to time. The worst so far
for me (having used Arch for only a year or so) was the Xorg 1.4 update
which totally borked my ati setup. I'm now running the closed ati drivers
until I have time to try the open ones again.
That being said, I've had more lockups requiring hard reset in the last
week of running the Ati closed drivers than I did all the time running
Arch, Gentoo (years) and cvs/svn builds of KDE3. Closed sucks.
