You have a point. I think it depends on the area of computing you are looking at. In computing as a whole you are right, it is going to be a long time until people stop replacing the office applications with browser alternatives, for example.

Where browser apps really shine is in workgroup applications, where networking and cross machine communication is needed, whether the client is application or browser based. Then it becomes an easy way to upgrade and support the individual users without some of the issues I wrote about above.

You have a very good point about networking though, we have a long way to go on that road before it is considered flawless!

PC means personal computer and this personal usage model worked so well and adopted so widely for plenty of reasons.

I don’t think networked stuff has a chance to dominate before networks structure evolve further than ancient Ethernet and crappy wireless links.
