Funny thing to notice: even if Nokia has screwed up big time with this whole Maemo / MeeGo / Harmattan thing, it seems that they are still the only one actually capable of doing (and achieving) something.

Intel is totally lost in mobile and apparently have no idea what on earth they're doing, they're just doing something.
