I am an huge mac fan, I use apple everyday and will never use a PC. I had a friend who wants to buy a good used mac. He wants a higher end G4 (Dual 1.4ish) or a 1.6-1.8 G5. He asked the question "what justifies me paying 1000$ for a 1.6Ghz computer when he can get a 1.6Ghz PC computer for a fourth of the price". Now I know it is like apple and oranges but I couldn't give him an answer.. So my question is what can I tell him to convince him. Other than the usual no virus and the mac osx vs. windows answers what can i tell him.. I guess more of a technical answer.
