It's all niche ptoducts with no reach, though. I'd like something mass-consumer-oriented and ubiquous, so I can actually get (roughly) the same experience everywhere from bus stops and coffee shops to my office. The current situation is like pre-ipod mp3 players: the tech is all there, the ux and marketing effort is not.

Amazon WorkSpaces is just VNC/Remote Desktop-type tech. You get a desktop computer in the cloud, which you connect to as a thin client. Performance is exactly what you expect -- pretty bad, but probably okay if you're doing simple things like word processing or order management or call center stuff.
