I broadly agree about complicated apps, but there are plenty of mobile websites which are more useful than apps for me precisely because of their simplicity. The killer benefit is the ability to deep link, for instance I have three or four icons on my homescreen going to the timetables for different bus stops, and two or three for the weather for different places. For my use case I want to go straight to a simple stateless page which tells you what you want to know, not be subject to the UX whims of the app designer. The drawbacks are created by iOS, I would prefer these websites to be able to use a cache which worked and wasn’t broken in small subtle ways, and to be able to set them fullscreen.
