Other converted PC users rejoice that they no longer have to run antivirus or spyware programs anymore on their Mac, which is something that I still do not do on my PCs or Macs (yes, I own 4 PCs). The shift of the Mac user base from the generally more computer literate to the less literate will be interesting. The iPod is simple, powerful, and successful. Although the Mac is built around the same concept, it's a computer.
I have found, working with other people who aren't very computer literate, that they prefer a static setup, be it Windows or Mac OS. They want everything to look the same, nothing to change. All they want to do is check their e-mail (or whatever it is). So you can (or can't) imagine how a switch to a Mac from a PC can become traumatic for those accustomed to Windows.
The same can be said about the switch from VHS to DVD. Other than video geeks, it takes a couple years for the masses to make the switch. The switch usually comes with a hardware replacement. For example, our VHS player stopped working so we bought a DVD/VHS combo about six years ago. When that dies, we will probably just get another DVD player, especially considering the status of the new formats. So, Vista is what is bringing PC users to the Mac OS. Their XP machine needs replacement, and fearing Vista (or after experiencing it), they get a Mac.
