Thanks for the welcome, good to know there's quite a few linux users around.
Mark, I rely almost entirely on Pro Tools, which of course only runs on windows (badly) or mac, or a hackintosh in my case. But there are certain things I do on one of my linux boxes, like more creative sound design, including csound and pure data. Ardour's saved the day a few times when I needed emergency Foley recordings and didn't have my proper rig with me.
I think I'm away on the 2nd Nev, but if not I might see you then.
