Anyway, Arch is interesting. I first tried it some time in mid 2004 and it was just too flakey for me. Various packages were broken and it felt pretty unstable. I remember there was a lot of talk about how wireless did not work well in Arch at all and how the GNOME desktop builds were severely borked.
I have now tried it again and it's much, much better than before. It still seems that there are occasional package problems, such as recent problems with initrd, but, overall it's a very, very nice distro -- one of the two or three that I tend to keep on my spare boxes longer than a few days. In fact, I am now running Arch full-time on my secondary workstation (Slack is still on my primary) and if the stability is there then maybe I'll find myself using it more and more. I prefer the pkgtool package manager in Slackware, but pacman's dependency checking is a real advantage for many users. I know I found it great when setting up basic post-install stuff, like flash, java, artwiz fonts, codecs, etc.
One thing that I have not figured out yet is whether Arch has a true "stable" branch with security updates etc. like Slackware does. It seems like the answer is no, since their brances are listed as "current, extra, unstable, and testing." Those words sound like everything but stable.
It seems that most Arch users are happy using the distro, although I have come across some rising dissention in the ranks with regards to package problems, the Arch philosophy, etc., such as this recent thread:
http://bbs.archlinux.org/viewtopic.php?t=16833
but every distro has unhappy people, I guess.
So, I doubt I would run my servers on Arch, but IMHO it seems to fit very nicely in between Slackware and Gentoo as a desktop distro. I can see that maybe someday I would switch my day-to-day desktop to Arch and keep Slackware or Debian on my other boxes.
Just my $0.02.
