> Finally, as a nitpick, moving apps to a different workspace instead of minimizing to taskbar/systray seems like much more work to me.

I specifically want to reply to this, because it is not at all how I use workspaces. I almost never find myself moving an application from one workspace to another. Instead, I switch to a new workspace before opening the application (causing the application to open on the new workspace), unless I know I want to use the new application at the same time as an application on an existing workspace. Switching workspaces essentially replaces alt+tab in my workflow.
