Answer to first question: Every single one. The answer to your second question is manyfold. First, it makes a false presupposition, web development is not faster and easier. Second, most devs probably chose the browser as a platform because Apple was so tremendously successful at creating artificial "application barriers" -- making it uneconomical, problematic or even impossible to create well-behaving cross-platform applications. Building application barriers used to be Microsoft's primary concern (they invented the term for internal correspondence), they fought hard against Sun's original vision of Java, but has become Apple's main trump card for while, after Apple decided to give up making great and innovative hardware. Third, mobile apps became sexy but the fragmentation is too high (even just Android is way too fragmented). So many devs and companies bite the bullet and decided to make a web page for desktop and mobile phones/tablets as a least common denominator. If you disagree, show me one non-trivial web application with the performance and a user interface that matches or outscores a corresponding native application, and we can discuss why it's better than the rest and an exception. So far, I haven't seen a single example but there should be one or two.
