I don't know how important this would be to the general audience, but as a musician what I'm waiting (and would pay good money for) are songs where I can break out individual tracks to better study what the artists were doing. This is especially useful when, for instance, a guitar player double-tracks playing slightly different riffs - I have a hard time hearing them as separate entities in the final mix. If they are developing a different standard then why not craft if so 3rd party authors can easily build 'sheet music' and tablature scores that sync in automatically with the song?

Not only do many industrial HMI products use Windows, but it is almost always the only option for PLC programming tools, motion controller software, variable speed drive and process controller configuration - you name it. Linux-based tools are few and far between.
