I could probably make fun of Audacity for not keeping up with the times, but if you look at other DAWs you'll see none are exactly bastions of good interface design. I got a little more serious about my music last year and decided I wanted to invest in a nice DAW, but after demoing I few I felt completely unimpressed. They're nearly identical to how they were 15 years ago, other than my PC being much more powerful. I ended up just sticking with Reaper, and hoping something comes along someday to mix the industry up. Proprietary dongles and tiered versions of the exact same software with gimped features doesn't cut it for me.
