Apart from LiteStep (the description and link to which is found over at thebombsite) any others of note worth considering ?
(Note: I said ‘shells’ not ‘alternate OS to Windows’ :) )
Update: Screw LiteStep. 3 installs. 3 crashes, one of which even stopped a Restart, winamp controls that cannot be removed and 10 themes downloaded all of which failed to install. And this is a stable release ?. Wow… I’ll be the one not going near cvs then.
