Well, if a web application is used, then all the PC is doing is being a GUI 
interface ;)

And for a lot of things these days, on many peoples desks the PC isn't doing 
much more than I am suggesting. Think in terms of a front end to an SQL 
database somewhere else, a means of getting at email on a corporate server, 
a means of displaying something got from somewhere out on the web, if Google 
and others have their way it will be a front end for all office applications 
...

The way we (as in us engineers) use PCs as an instrument in their own right 
is a very small percentage of the way the world works.
