Yeah, I've used like Citrix desktop before at my job, but I'm still using a computer to connect to that. I was thinking just a screen that just has the basic ability to connect to different cloud hosted VM's, and no OS other than that. I'm not sure I've seen anything like that before, either for enterprise or consumer.

I think as years go on the network access issue becomes less and less of a problem though. Plus, for home dekstop computers there is pretty much constant access.
