It's about security and ease. If it were secure to install arbitrary code on a computer, we'd have more apps. If it were easy to compile across platforms and handle every weird OS call, we'd have way, way more apps. Browsers are essentially a translation layer with some security guarantees and even there, on both counts they aren't perfect. They're merely better than the alternative. If you ever want to disrupt the entire industry, make something that is easier to code for and more secure than a web browser. If it's faster too, then that's gravy.
