I have a new window manager and it works great. There are a couple of minor bugs (my gvim window runs a little off the bottom of the screen), but it's only the first release.
(although readers should note that I've used ion for years so the switch to Xmonad may be a little more jarring for some.)
And while I'm typing, I just want to say how spot on Ed Felten is in this post where he talks about the (increasingly loud) chatter about a “clean slte” design for the internet. While we're talking about things which will probably never happen, checkout ipv6porn (don't mind the domain name, it's perfectly safe for work).
