Not sure the compressing/obfuscating of scripts makes the application model similar to a Java/Swing or a Flash/Flex model. The granularity for a Web app is infinitely greater than an Swing/Flex app. Having the UI Structure (HTML), Style (CSS), Logic (JS) interpreted at runtime allows the server to take generate dynamically many part of the applications. This is the big difference, not that the scripts are compressed/minimized. Now, I agree, some applications overuse AJAX, and often, single page is an overkill with lot of drawbacks and complications. But the big sites, such as YouTube, Facebook, seems to be using these technologies the right ways.
