Macs are more user friendly than PC. I don't think anyone can refute that. That, along with Apple marketing and product aesthetics attract "on the fence" consumers to their stores. Granted, the iPod/iPhone halo effect has helped a bit, but Microsoft didn't help the case with Vista. It may be pretty, but it's just not user friendly for the typical PC user. If said user didn't understand how to effectively use Windows XP, do you think they'll understand Windows Vista?
Enter Mac OS X. The pretty colorful dock, dancing icons, and catchy commercials suck them in. NO program permissions, drivers, antivirus programs, etc., for them to deal with anymore. Yes, these "on the fence" consumers are probably the same PC users who rarely update virus definitions, delete important system folders, and open bogus IRS emails. Steve Jobs welcomes you, your computer ignorance and checkbooks with open arms.
Apple marketing is very effective at making you think that what they offer, although inferior at times, is exactly what YOU need. (MacBook Air) You don't know why or what you're buying, but you know you have to have it. This may be marketing 101, but coupled with the fact that it's trendy to own anything related to Apple these days, and you have a lethal combination.
With that in mind, I'm curious to know why you folks out there who have asked for advice are considering an Apple Computer.
