What the commercial fails to capture is that while all these people are "PCs" they are also dealing with a CRAPPY, over bloated, non-compatible, safety-impaired operating system. It's just like "The Mojave Experiment" - why not show people using Microsoft anything and show their reaction while doing so. It's going to be decidedly different than "I'm a PC" - my reaction... Whoopee ***** doo for you.
Crappy? No. Bloated? Not more than OS X, the reason why Apple is reworking it with Snow Leopard to reduce bloat. Non compatible? It's compatible with over a hundred thousand applications, and over ten thousand peripherals. Compare that to the Mac please. Safety-impaired? OS X has been proven more insecure than Vista and basically every other modern operating system.
Fanboys...
Why would Microsoft need to show people using anything? Does Apple? The reaction would be just the same as any other. This works, and lets me do my job, or play my games. Big deal. Look at the windows.com site with all the users uploading their "I'm a PC" videos. Why would they if they hated it so much? Why can't you learn that a computer is just a tool, and PCs enable billions of people to do their jobs and hobbies just like the Mac does for a few million. Both have strengths and weaknesses, just like both companies do some things wrong and some things right. Why does it have to be a religious thing for you?
