Painful lessons
Makes me think of the endless number of meetings I've had over the years with various clients, where I've argued that a mobile optimised, or "responsive" web service, would be a better option than dedicated "apps", only to be told that "everyone else has an app", or "most users prefer apps" - usually by some marketing bod with little or no technical knowledge. I suspect "most users" would be perfectly happy with a mobile website if they understood the different security models and their privacy implications. Well, maybe now they're beginning to!
