It seems unfortunate to me that the Canonical designers didn't just start from the very functional, very slick Gnome 2.x releases and improved and polished them while keeping a stable base. Instead there seems to be a need to reinvent a usability paradigm that worked extremely well and gave users a lot of power while keeping a level of simplicity which, while higher than that of mobile interfaces, is in most ways appropiate for desktop interfaces.
