Say I open 3 browser windows and surf in each separately. Would this be much different than if I ran each on a separate desktop? Really you're only using more memory/resources for running the desktops themselves, each of the browser windows are still running.
In my case, my only resource that is lacking is the screen space. I typically have a programming window open, a few file browsing windows, Word and/or Excel, then browsers to test in. It gets kind of cluttered trying to keep track of where I have stuff running.
Where you don't have the system resources to run multiple apps all the time, it probably wouldn't make sense to use the virtual desktop anyway.
