And after reading this article I (you) still have no idea what a hell this virtualisation is.

HAHAHAHAHAHAH so true LOL 
XD

It would have been probably a bit too daring to explain the big V in an INQ article, though.

That's what Whackypedia ist for:

This is no news for me, I've been in IT consulting for a while and I could safely say that at least 80% of my clients do not have a clue about virtualisation and why they do or do not need it. Its all a consequence of peter's principle and trying to push skilled techies out of decision making roles. Serves them right.
The funniees thing I ever had to do was explain to them why they cannot stress test an application on a vmware session. They are all into virtualisation, but their minds are still stuck in monolithic server configuration.

And after reading this article I (you) still have no idea what a hell this virtualisation is. 

Thank you for nothing ;)
