Your argument is flawed. First and foremost, you cannot compare different brand processors by the amount of MHz they have (See:
Why AMD-MHz don't equal Intel-MHz). A calculator runs at 15 MHz. Does that automatically make it faster than a Sega Genesis? Heck no. There are more deciding factors than just MHz when it comes to processor speeds. Essentially, what you're doing is comparing apples to oranges.
As for what you said about the ease of use, I find it to be quite the opposite. I've worked with OS X before, and believe me, it's a lot more difficult to diagnose problems. The lack of any real visible sophisticated diagnostic tools such as driver viewers simply baffles me. I remember how this one Mac would only boot up into OS 9, and upon a full system recovery, the sound stopped working, and I lost access to various programs.
OS X is not at all idiot proof in the way that anyone can permanently delete a program just by dragging its executable into the Trash. This has happened to me on several occasions, and it is very bothersome. Additionally, what you have said about OS X not requiring the use of drivers is poppycock. For any new piece of hardware you're always going to need a CD to install drivers. That's a fact of computing. And it wasn't until OS X Panther that driver installation became automated.
What you said about OS X being better for animation and programming is debatable, and I know for a fact that it is NOT better for gaming, simply due to the lack of games for it. Remember when it was advertised that Halo would be for the Mac? And the video actually showed it running on a PC? It was never released for the Mac. And voice-commands? Please. They're just a gimmick. They don't actually help you get anything done. They just let you speak a series of pre-defined messages for pre-defined actions that you could do much faster without the need to speak.
And security problems? Of course you're going to have security problems on an operating system that's gone
mainstream. With so many programs available, and so much development committed to the Windows platform, it's only inevitable that you'll find things like viruses. That's a fact. Deal with it. It is your responsibility to protect yourself. Going for a Mac to try and avoid these problems just shows that you cannot learn to face them yourself. And remember, OS X gets security updates too, so it's not like that operating system is 100% secure either.
So in conclusion: stop assuming that Mac is better just from what you hear. I've used OS X before, you haven't. Any OS X commercials are basically just like political ads - they only tell you what they want you to hear. I honestly can't see how an overly-simplified operating system can make computing easier to cope with.
