How About a Chromebook on Steroids?

The recent purchase of a Chromebook for my son got me thinking about a new opportunity for Linux on the desktop. This is not an idea for getting a standard GNU/Linux desktop to automagically replace all existing Windows desktops, but to leverage the cloud computing paradigm with a bulked??-up Chromebook-??like system that would be workable for 80 to 90 percent of personal, school, and business needs.
