I can't speak to the iOS experience but can for the Android experience and I have most certainly encountered the "dead end" as the author calls it with Android apps and OS. I actually have not encountered any "dead ends" with Win 8 (yet) but have with other Windows versions as well as Mac OS X and various distros of Linux.
I understand the point the author is trying to make but disagree that it's the biggest hurdle for Win 9 to overcome.
