P.S. It's much harder to install new languages on a PC than it is on a Mac, Dvorak included. Plus, the Mac conveniently allows me to decide whether I want to use Dvorak in all of my programs or in some of them. The PC decides this for me, and it makes the wrong choice.
This of course does not answer the great Mac v. PC debate - most people who DO debate seem to know more than me about hard drives, RAM, security, Gigamajiggers, and other things. I find the OS to be elegant and efficient, I can leave my Mac on for weeks at a time, and I have never had it crash (had it for over a year). This is much more than I can say for Windows, which I have been using in all its iterations since 1998.
But! But! Here's the problem. If one of the platforms indeed DOES have a superiority over the other, the person who uses the inferior platform will be forced to deny that there is a problem, creating a fanboy flamewar that has no purpose other than to justify the thousand dollar purchase. It's like we can't see the trees for the forest (if you'll let me say that): we're so concerned with who "wins" that we can't understand that Macs and PCs have many many many differences, and each has strengths and weaknesses.
I find that most flamewars seem to be justifications for isolationism rather than qualitative and quantitative comparisons of fact and opinion (see: Halo thread, the Sony fanboys of yore, etc.). I own a Mac. I switched because it had things I needed. I think PCs are worse, but I have to admit that there are things I can't do with my Mac - I wish PC users would admit the inverse as well, but we've grown as a society to believe that blue screens and daily reboots are just a part of computing. Oh well.
