What everyone is up in arms about is the fact that people want desktop applications. We need some applications that can do meaty processing. We want applications that use up every drop of CPU be it graphic design, photos, video editing, audio editing, software development, games, etc. When we are running on a desktop or traditional laptop we don't want to be switching modes/environments. We simply want and need the desktop environment to continue to run the applications we need and enjoy, and indeed show no signs of disappearing anytime in the foreseeable future.
