A constantly usable testing distribution for Debian

aptosid is focused on being derived from Sid, which is the unstable branch of Debian. It's far more bleeding edge than Testing. (Current kernel - 2.6.35) It's very nice for those of use who like to hang out on the slightly-hairier edge.

I currently use it on my desktop and laptop. I started on the laptop because I needed the very up to date kernel for harware support, and I wanted to try an XFCE desktop. Liked it so much I moved my desktop to it.
