"low quality content on PC" is completely wrong. Some of the best programs around are desktop software. Samplitude, Sublime 2, Studio One 2 are a brief few. What happens in your circle of friends does not represent anything and is one of the reasons why I think Facebook is so unhealthy for the younger generation. BTW if you do real pro audio/video work you are not going to be using Linux simply because most "Pro" audio/video does not come in a Linux version.
