This is true. Instead of "one machine == one person" we could adopt "one virtual machine == one person" or even "one virtual machine == one app". It's too much to ask mainstream users to understand how to do this but it's not too much to ask operating system designers to support it in a way that's deeply integrated into the OS (not something layered on top in the way we do it today) so it's transparent to the user.
