That's kind of sily. You need some local hardware to run that virtual desktop environment, handle grapics and streaming. That means it's powerful enough to run a browser and some basic apps locally, what covers most of what people need. If you do need a virtual desktop for the few things not covered by a basic browser, you probably pay a lot for the privelege. Then you get people living in a region with bad internet, like rural places, who'll get fed up with laggy performance in no time.
