XYZ Corp. switches to Windows,' etc. No-one knows about FireWire, or that QuickTime, the multimedia standard even in Windows, is an Apple technology. People are stunned to hear that your Mac can be made to run Windows as well, with fewer crashes than on Intel machines, and jaws drop when you tell them how hard it is to find a Mac slower than 200MHz, and that 300MHz exists with 500MHz-1GHZ on the very near horizon. All they know is that Microsoft and Intel are big names, and that Quake is fun.
People are stupid.
If everyone chose technology based in quality and capability, the world would be a different place - BetaMax VCRs, MiniDiscs and Macs would be everywhere. Wintels sell despite the fact that everyone who has one is constantly complaining about why it doesn't work properly, how hard it is to use, and oh how confusing it all is. But they buy them anyways because they don't know better, because people are easily swayed by image. Apple marketing is the worst in the business. Apple ads appear in Apple-friendly places.
