Just like the purpose of land-line communication has changed from voice calls to data, so is the purpose of browsers changing from document viewing to applications. The browser as a rich app platform is a good thing. It takes a lot of worry away from end users (upgrading, security, installation, ...). In the long run, we're all going to have better and easier to use apps because of it. We're finally going to be able to get rid of our personal computer as a physical piece of hardware. A PC should be a metaphorical construct that follows you around as needed, regardless of the hardware involved. The web is the only credible way of doing that.
