The problem is that the article sort of glosses over the fact that it's using a single machine.
It mentions VMware, but only in passing, and doesn't mention that you need to install an operating system on the virtual machine.
Yes, it's a good use of TB and it's light on resources where most of us need two machines, but it really makes the single machine=real pc+virtual pc a lot simpler than it is.
