Meet the ubuntu (or rather unity) menu; will you call this an innovation?
The ubuntu desktop never stops to amuse and never stops to innovate. The ubuntu unity packs in with load full of features and one never stops to wonder how much thought have been gone into come up with all those ideas, if only some efforts was also put into the planning and implementation of those nice ideas.
Many times I felt that the developers are are so immersed with developing features that they fail to step back and think how to go about the implementation and thus fail to attain the best possible implementation of those features. Instead of as a feature many of these innovations appear to be as an annoyance or a bug.
