Tux Machines (TM)-specific
#! is a lightweight Debian-based distribution that uses Openbox. While it is not technically a rolling-release distribution because it is pinned to the stable release, there were tons of preview releases for this version. Now that Debian 7 "Wheezy" is finally stable, so is #! 11 "Waldorf".
I tried this on a live USB made with MultiSystem. To be honest, as it turns out, very little has changed from the preview release that I tried almost a year ago; you can read that article here. Rather than wasting electrons by rewriting the same words, I will simply list what has changed.
