Dont be to hard on Linux, its growing every day. Linux doesn't have any realtime hooks into the kernal, which I think is the problem for audio applications, but there's still some usable stuff available. MiXViews is alright and the guys at AGNULA look like they are getting somewhere. Things are starting to get interesting with the 2.5 kernel and I think Linux can be a solid platform for this type of work. We just need some major players to get involved and port their applications over to Linux. It will happen...
