I realize that these are mean and not true many times, but they are so damn funny. My newest favorite is the Vista Security Guy.
They are all good, but that one hit my funny bone today. I laughed out loud because we are currently dealing with a lot of Vista security issues with our ActiveX setups.
Apple gets my vote for marketing ingeniousness. Here is a single link to all their commercials: Apple - Get a Mac - Watch The TV Ads. :) They are getting people to relate the old business nerdy guy with one OS and the hip youngster with the other OS. The best part is that the Apple kid is really nice and sympathetic, whereas the PC guy is a real geek and just "doesn't get it".
Again, I'm a PC guy, but these are funny! I hope Microsoft comes back with a funny ad campaign. It makes for good TV!
