Arch Linux is just awesome, is one of my favorite Linux Distributions
Here a nice Review of it from Linux Journal Magazine

You love tinkering with your computer. You've tried Ubuntu and Fedora, and they're good, but you feel something is not quite right. Maybe you don't like all those daemons loading on boot, or maybe you want to build your Linux desktop stack just how you want it

Simplicity

Arch development is guided by simplicity. The Arch wiki states, "Simplicity is absolutely the principal objective behind Arch development."

Rolling Release

Arch uses a rolling release model. This means that the repositories are updated frequently with the latest stable packages from upstream developers. The advantage here is that you don't need to reinstall or do a complex upgrade procedure every six months.

BSD Style init

Say bye-bye to complicated System V runlevels and their associated symlinks. Most distributions use a System V style init, which has a separate directory for each of its eight runlevels. Arch uses a BSD-style init system, which accomplishes much the same with a simple set of scripts. Need to add CUPS to start at boot? Simply add CUPS to the daemons list in /etc/rc.conf. Done.

You all know I really like Arch Linux, together with Debian and Slackware it is my favorite Linux Distribution.
Here is a good Arch Linux review by Susan Linton.

From Slashdot: "Arch Linux current version is 2010.05, but Arch Linux is a rolling release distribution, so this version is only the snapshot of the Installation image, Arch Linux is suited for the experienced Linux user, but the mid-experienced user may also try it.
There are a lot of good reviews of it, I have found these two really interesting ones."

Good review of Arch Linux which is my favorite distribution.
I really like the simplicity of it, and talking about being unstable, it really is not.
I have been using it daily for more than a year now, and have o only faced small issues that were solved fast (minutes of googling)
I have some tutorials about arch in my blog, http://www.go2linux.org

I have not tried it yet, or.. maybe yes., I am actualy using Arch Linux on all my PCs and Laptop, with OpenBox as my window manager. I loved the idea of Crunchbang when I heard about the project, I inmediately tried that but based on Debian, and with fluxbox http://www.go2linux.org/installing-a-light-linux-operating-system-debian-fluxbox Then I discovered Arch and felt in love with it, Now I have found ArchBang, I will have to find some time to install it. http://amplify.com/u/basb
