That is true, but if you want realtime audio and low latency, you need to use jack. And also, the firewire cards (at least the FFADO) work only in Jack. I like the idea of having audio concurrency, which is very good for day to day desktop use, but for professional audio that is not good. I think that Linux shuldn't imitate the bad things in MAC and Windows. If you want Pro audio, you use pro drivers and thas it. Asio came for some reason....
