I agree that for real world back-office type database enabled applications
"fat client" beats "server-only" hands down. However, I would not discount
browser as "the best business application platform". Late versions of IE
(i.e. 5.5+) CAN be effectively used for "fat client" types of applications.
Few things often overlooked by "cross platform/browser" developers:
1. IE5.5+ supports behaviors/custom controls that allow complete
encapsulation of shared javascript code.
2. XML support is world-class, with shared code model allowing
javascript objects within XSL, thus allowing complete segregation of data
from presentation and high performance model/view controllers.
3. Support for business functions such as customizable print and print
preview and "user settings"
4. Customizable HTTPRequest and WebServices allowing true distributed
model.
5. Direct integration of business applications (including Excel and
Macromedia) via XML
As a matter of fact, in the last few years we were actively converting
existing client-server applications into the browser based model. We ended
up with automated conversion process (via XML of course) that was producing
less javascript code than the original PowerBuilder/PowerScript application
while providing identical look-and-feel, functionality and API for the
developers. Following are the links to the articles in XML Journal,
PowerBuilder Journal and XML DevCon 2001 presentations on the subject:

As far as Java on the client goes, the upcoming version of JavaScript
supports object inheritance, implementation of interfaces, precompiled
distribution and shared run-time with C#, VB and C++. Given the "average
developer" skill set in business organizations (imho) JavaScript has better
chances for "language of choice" for business apps than the Java and/or C#.
