I remember some years ago, when most of my computer usage was playing games, many of the software games purchased were "hybrid" (i.e. would run under Windows or Mac). I was using a Quadra 650 and later a PPC G3. On the documentation that described the install procedure, I recall that the Windows instructions were quite involved (many steps), however the Mac went something like, "insert the disk, double click the installer". I believe this alone speaks for the simplicity of the Mac OS. Nowadays I seldom play games. I use my Macs for many different things. I use a Windows machine on my job, (that's all they have), we are running XP & 98. I'm not really great with technical discussions, suffice it to say that the Macs just have a better "feel", seem more intuitive, and less prone to application slowdowns or locking up. Just my 2 cents worth.
