A mobile site surely isn't a silver bullet and has a bunch of shortcomings that make it inappropriate in a lot of scenarios. And the IE-support misery is only one of those scenarios.

That being said, my article is heavily focussed on negative aspects of mobile development. I got to clarify that I highly admire and appreciate a well-crafted native application (on mobile as well as desktop). I have the utmost respect for the developers that create those with the available tools. I just don't want to be one of them anymore (:
