Don't really get your post tree. Although there is still a lot of scepticism in the record industry about the likes of iTMS (some of it is fair enough, a big shift to downloads will effect the amount of money labels have to put into A&R and promotion. I'm not saying that things are great at the moment, I'm not a fan of the big 5, but on the other hand there has to be a balance. Anyway....), even the more hardcore anti-corporate labels such as Kill Rock Stars are now on board. Everyone, the big labels, indies and most artists, seem to love iTMS as it finally offers a viable alternative to P2P downloads.
I'm not sure if tree was talking about Apple hardware but you're right Quicksilver, Macs are the industry standard for music production, graphic design and publishing, and are also very strong in video and multimedia. Your last comment is maybe a bit simplistic as most major programs such as ProTools and Photoshop are cross-platform but you do have point.
