Eric posted the Mac vs. PC speed results links I sent him. I have to take exception with his conclusion that "The Mac is ‘easier’ to use, and it is really pretty, and we don’t use it because it’s fast. That much is clear."
The tests clearly show the PC is faster in pure processing speed, but except for super processor intensive activities like rendering, I still claim I work faster on my Mac – plus I enjoy it more. 🙂
