There seems to be this idea in the Mac community that PC users perceive Macs to be slow and this is the reason they don't buy them. This isn't true at all in my experience. The only people who care that 2.7 GHz PowerMac G5 is 0.8% slower than the fastest Intel or AMD processors are internet-dwelling computer dorks who really have nothing better to do with their time than argue about crap like this. In the real world, you don't ever see people try a Mac and walk away saying, "Boy, I would get that iMac G5 if it wasn't so darn slow". There is no perceivable performance difference between Macs and PCs so most people don't care about this. There are a lot of other misconceptions out there that prevent people from getting Macs, but I've NEVER heard a real-life person say that Macs are slow. If this Apple-switching-to-Intel rumor is true, there is more to it than the myth of the "MHz myth".
