Microsoft released a "Made on PC" stop motion animation, showing two personal computers (PCs) on a flight. One's running Windows 7, and the other Mac OS. The Windows computer fires up Avatar on Blu-ray, and the Mac is portrayed as envious: "So cool ... It's like we're really in it!" I watched the ad on a Mac. In 1080p. Maybe someone didn't think this entirely through.
When Microsoft Office 2011 came out on DVD, I tried to install it on this Mac, but the disk just ejected. When the disk worked in another computer, I realized that it was the first disc I'd tried to use since buying this Mac. Apple's Genius Bar swapped the drive in under an hour and I was able to install, but I realized our distribution methods have definitely changed.
So that's cool, PC. You play discs. You probably have a serial port too.
