Is that bad? That's like complaining there's too many websites on the internet. Why create a messaging system on youtube when people can email? Why create google talk when I have a phone? Why use Linux when Windows fits all my needs.

My point is that one size does NOT fit all, and we should stop pretending like it does, web browsers are great for getting your feet wet, but it's a lot easier to get even richer experiences with native applications. By that logic, there's no point in applications period, and we should all use some variant of ChromeOS that only has a web browser, because it could be argued that "Everything you need to do can be done from a web browser." Sure, and for some people that's fine, but native experiences are undoubtedly richer.
