Well, the nice thing about building a product when there is already one that exists is that at least you know there is a market that is ready to pay for the service. The bad thing of course is that if you can't bring some kind of disruptive tech to the battle, the entrenched player is probably going to stomp you. Start-ups win against entrenched players when they can move faster, thanks to leveraging a new technology, whereas the older competitor continues to lumber along using technology that was optimised for a time when hardware or bandwidth or whatever was more expensive. At any rate, I doubt that we have successfully filled the entire space of web apps. As bandwidth becomes less of an issue for example, we should be able to start doing video editing on line. Or how about a decent competitor to Garageband? That doesn't exist online yet, and yet there isn't really any reason that it couldn't be done right now.
