That's a really important aspect, are desktops going the route of developer only? (Non-web) Designers and other white collar probably don't need it, but they use machines that wouldn't notice the difference...
With FFOS, Android/Chrome, and MS there's a conscious effort to eliminate the difference in development between desktop, tablet and phone. With more people using computers, not as many people need or want desktop apps and those features on all of their desktop apps. If I suddenly need to edit an image, I don't need PS or even Gimp, I'm often fine with a web app.
