The iPod broke down the Mac vs PC wall
Yes, it's true that selling's iPods would also sell more Macs, but I remember when iPod became the best selling MP3 player, what I would tell my friends. For years there was this "PC vs Mac" mentality, with people VERY entrenched on their sides. The simple beauty of making the iPod the best MP3 player, was that even if you were a hardcore PC user, if you owned and really loved your iPod, it would be impossible to be an "Apple hater". Once you own a piece of Apple technology, and love it for its simplicity, ease of use, and intuitive design, you can't tell people you "hate Apple". Now you might take a 2nd look at a Mac, even though, yes, like a BMW, they are more expensive, but their quality of design and function make them more efficient and in the end, more desirable to own than the "best bang for the buck."
And like I tell my PC friends, "if you lose all your data due to some PC virus, how much did that PC REALLY cost you?"😎
