"don't laugh, alot of non PC-techies would do that. Just remove their personal files, and not realize they also have other stuff all over the machine."<p. In this case we're dealing wit a real "techie". To understand towers, radio band-widths, and rf communication requires a nerd with a combined religious/political zeal. It's no laugh.
I know people with PhDs, who can't do anything with a PC, they know nothing about them at the system level.
