"5. Smack, crack, hack and track any network with Linux (not Windows)
Ok, a bit more of Windows bashing here, but it has to be said. The best network "auditing" (and by "auditing" I mean "snooping") tools are to be found on Linux.
"In fact, the very technology underpinning the Internet -- TCP/IP -- came to life in the world of UNIX. That Johnny-come-lately, Windows, won't let you audit networks to the extent Linux can."
