Keith, its not all or nothing for me. I will keep my Mac Pro and use it for internet use, making music (Im a rock/blues guitarist) and a variety of other functions. Its still runs great.
I will use the PC exclusively for editorial stuff. I do need the raw performance of a PC in order to comfortably deal with the wide range of codecs out there. It will be on the internet only for updating and installing.
It seems like a logical way to proceed to me 😀
