XML Beyond the Browser

When the browser recipe fails Browsers are basically hypertext viewers with limited interactive capabilities. When the limits grow too large, you may want to build your own client in place of the browser.
Great customization If you go to the trouble of building your own client, you can make it do what you want, not what the browser vendors want.
Better tools than in the client/server days There are many more tools for connecting Web information to user information, and at lower cost, than there used to be.
Deployment headaches Deploying your own clients means that you may face a lot of work in installation, upgrading, and support, and that you can't simply rely on other services to take care of this for you.
