LOL... We do a lot of creative work (artwork and video) both in-house and with several contract shops, and neither us nor any of them use Mac Pros. All the creative professionals I've seen use MacBook Pros.
I totally believe you, I also believe the new Mac Pro and new iMacs have tons of power, that is why I am looking into an older Mac Pro. From what research I've gathered, even the 2009 8 core would be better than my MBP. I just like the ability to have internal drives and having the ability to use a better graphics card than mobile one.
