Yes, intentionally. No arguments here. Not only that, I agree with everything you just posted. Snobs suck, period. My neighbor does a lot of advertising illustration work for major magazines. she would probably be lost without her Apple. She has both. I have not noticed any difference on how Adobe CS3 runs between each machine, she has not either.
I don't know why CAD is not used so much on Apple's. I do know that since I build my own machines, I can build a really high end machine for a lot less than someone would pay for a retail Apple, but then again, that applies to a P.C. also, on the high end that is.
