I do have to say, it is always inspiring to see it in action. Reaper is a good thing in the DAW world, a revolution in development if you will. Everyone should be thankful for it, because even if you don't use it, it has certainly given other developers a push to compete with it. That's why I love it even if I don't use it myself (though I keep telling myself I will use it one day).
Both Reaper and Studio One have been fresh new winds in DAW development. Their existence isn't a detriment, but a really really good thing. Cubase wouldn't have been what it is these days if it wasn't for these two, for example.
