Why not start with an obvious one: - a car: Do you really need one or does it just feel convenient? A bit of a stretch (and not really possible yet as of now)

Why not start with an obvious one: - a car: Do you really need one or does it just feel convenient? A bit of a stretch (and not really possible yet as of now): What about computer / mobile device hardware? Right now we need those to get work done but do we really actually need to own that stuff and lug it around with us? After all, it's about the function a laptop computer provides (i.e. providing you with the hardware and software tools to do software development), not about the device itself. Nanocomputing hasn't progressed enough yet to provide us with a ubiquitous computing resources but why not treat computing resources as a utility that's available in any house or hotel? You just log in and have your personal VMs ready at whatever hardware unit you're sitting at right now. This would be quite revolutionary in my opinion.
