Sun's take on the smart client

http://developers.sun.com/prodtech/javatools/jsstandard/reference/techart/nexaweb.html

While Sun is very complimentary about Microsoft's strengths on the smart client, Sun's answer seems to be....put HTML on the client. One of their reasons is that “The skill-set requirements and the complexity of HTML are much lower than for .NET”. Are you kidding me? Last time I built a Windows Forms application I didn't have to test it on 5 different browsers. Don't even get me started on CSS and javascript. The metrics that I see suggest that it is no less than twice the development/testing effort for a Web Form over a Win Form application. That's conservative and sometimes goes up to 3-4 times.

Sun also fails to address the need for the occassionally connected/offline access application.
