Doesn't really have anything to do with their mythical ease of use.I know you don't mean the design of the machines...
And a PC can run OS X. Not perhaps quite as easily, but neither option is for the non-technical.I really didn't think the switch from Windows to Mac was difficult at all, but hey, that's just me. Remember, on a Mac you can also run MS apps like Word and Excel and that makes the change a lot easier... also Macs can, in fact, run Windows... Don't remember Windows being like that... Just saying.
Why would you want to run anything other than Word and Excel? But the Mac versions are quite different to their PC counterparts, so in many respects it is like learning a whole new application.
Switching from a Mac to Windows is also easy. Either way is easy for a computer knowledgable person.
In fact I'll add that you can hardly use something as trivial as a music player as an example.People who are naturally bad on computers can pick up an ipad or ipod and be using it within a few minutes without any help.
