A number of years ago, Novell released a series of Mac vs. PC vs. Linux commercials parodying the Mac vs. PC commercials. I think the commercials are awesome.
There are so many subtle meanings to quotes in the commercials. My favorite is:
Linux: "I keep up with the latest trends."
PC: "And people just share that stuff with you?"
It's an obvious reference to the open-source nature of Linux and how many people contribute technology to it for free.
