AAMOF that joke was more against myself and my first understanding of it :
here, in France and in my working environment, PC stands only for Personal Computer.
When reading your post, I thought "it doesn't make any sense" and then had to force myself to think about an other meaning for "PC"...
I get often sidetracked (?) when having to deal with the acronyms used in various posts. Most of the time a search on the specialized acronims web site gives me the answer... not always..
