Another "pro" for apps is that many / most of them run on your device regardless of whether or not you're Internet connected at that particular moment. A few require a connection but most simply run once they're downloaded and installed. With HTML5 you would almost always have to be Internet connected at that particular moment (and if you lose your connection, you're screwed unless the software is very carefully written - most isn't).

It has some merits but I see it as a step towards what Bill Gates used to call "dumb boxes" and away from stuff on your own device / platform. I'm not sure most people really want all their stuff in the cloud. I know I certainly don't. Some stuff sure, but not all my software, data, etc. I'm pretty selective about what I allow off into the aether of the Internet and what I keep on my own devices offline.
