I'll give you an easy out: you can write off this rant as a case of iPhone envy. You can do that, but you'll be wrong.
Phone apps are, for the most part, a bad idea. Once upon a time, a long time ago, online services lived in little walled gardens, with names such as Compuserve and AOL. Then it was discovered that open, common standards, namely the Internet and the Web, were far superior. The walls crumbled and openness prevailed.
Phone apps are an attempt to recreate the walled garden. That's bad and wrong. When developing for a phone, a platform specific app should be the last choice. The first choice should be a standard web application, optimized for mobile use (which means smaller screen and limited input capability).
There are four reasons to develop a phone app instead of a mobile web app. Two of them are good. Two of them are bad -- but are the predominant reason why phone apps proliferate.
