Regarding your point that native mobile software is easy to install: this seems true in the absolute sense, but is it true in the relative sense? There is arguably less friction in running a web app on your phone then there is going to the appstore, inputting your apple id yet another time, and waiting for yet another app to take up valuable screen real estate.
In my opinion, the limiting reagent preventing the mobile web from overtaking native app development is clearly not ease of installation - it's performance, which davidhariri argues is changing rapidly.
