The text rectangle is now bound without the addition of white space. Developers want to provide their own user interface, just as any Win32 application does. The operating system makes a file association for .hta files, so that it knows not to start a browser instance, but rather to use the HTA application to run your file. Content authors can spend their time worrying about the content they have to write. Designers can determine what interactive effects can be added to the content without having to worry about scripting.
Engineers can concentrate on implementation.
This means you can take advantage of your Win32 development to create Web-applications that run seamlessly within the Windows environment. The end user won't be able to tell what underlying technology has created the application. The user only sees an application that works well, both alone and when interacting on the Internet. All this, and you don't even have to sacrifice performance. Be real nice to Nancy Cluts , developer-technology writer extraordinaire, and maybe she'll take you for a ride in that gorgeous red convertible.
