Now you have me confused. People are watching videos on the Web, so they need 3GHz chips. Applications which require 3Ghz chips are not economical for use on the web and should be on the desktop. I think there's been some disconnect here, because it seems like a totally nonsensical discussion from my point of view.

Anyway, the definition of a "Web app" can be stretched quite a bit with special plugins. People are apparently satisfied to stick a plugin in the browser and call their desktop application a "Web app." The defining feature of these "Web apps" is that they do not require installation. A native-code plugin can make quite effective use of system resources.
