good luck. i also spend most of my time in linux except for running Live and other audio software.
I have got Live running under wine other stuff doesnt yet run under wine which i like using (SoundForge, CD Architect and loads of VST plugins)
still, there is plenty of good music software for linux and you also get Jack / NetJack. which is a great tool. (ok i know it runs on OSX / Win as well, but linux is its main platform)
I think my ideal situation in the near future is to run 2 machines, one linux and one windows and use a combination of NetJack and OSC to combine them together. (NetJack for audio, OSC for messaging and sync)
Dont forget energy XT 2 also runs on Linux, its pretty cheap, really fast to start (especially compared to the glacial startup time of Live) and seems to be picking up progress again.
Even if most of the eloquent respondees here arent interested in how you get on, I definitely am
