While I do agree that web browsers could be the future, I expect it will take a long long time for the industry to transform. Given that some many browsers and standards on the market these days, can you take the risk to develop an application just working on Chrome? Even you do, if your customers don't like Chrome, you have no way to reach them. At the end of the day, you still have compromise with customers, no matter how great Chrome and HTML 5 are.
