I've heard complaints about the iPod but really no more or less than about any other mp3 player. They all have problems, it's just that the iPod is so hyped that when it has problems they stick out more. Hell, people expect Microsoft products to ship with a dozen problems now. They'd be gobstopped if one didn't.
Anyhow, that said I don't claim that my Mac is superior in any concrete way. What I will say is that while I am functionally proficient in the use of Windows, I have never found it to be a comfortable experience. If I'm sitting in my room, unwinding from a shower, and not wearing any #####, I would rather be leaned back and letting my chilis hang out in front of a Mac than a PC because it is a more comfortable and relaxing experience for me.
That said, there isn't a hell of a lot I actually need to do with my home computer: I use the Web, I legally acquire comics, TV shows, and music to read, watch, and listen to respectively, I chat on IRC, I write papers, I play open-source Roguelikes and legally acquired antique video game ROMs. Occasionally I chat with people on Skype. If I were a hardcore computer gamer, programmer, or other Person With Need For Superior Computronics there might be a problem, but since I'm not I'd rather have my computer be something I'm comfortable using.
