Since you were replying to me earlier, I explicitly welcome choice -- as long as the big players cooperate on common desktop infrastructure so things interoperate. However, when people actually argue that there is only one way to use a computer and running anything else is wrong (like the guy I was replying to earlier), then these people have lost all sense of reality.
I think it is good that GNOME dares to go in its own direction. Because I like that direction. There are already a ton of more or less similar desktops, so I fail to see why GNOME should "fall in line" here. Since choice seem to be so important for a lot of people, GNOME going in a different direction should be a good thing, right?
Once a desktop stops doing what people need it to do, people will not spend years changing their habits, people will flock to software which lets them do what they want. KDE learned and has listened to people's complaints after early KDE 4 versions removed functionality, and it changed for the better as a result. Now it seems like GNOME will have to learn the same lesson.
