It's not about "real men". I gather your knowledge of how expansive things can be and actually are with the Mac Pro in the professional world is limited. One example of what you can't do with an iMac is install third party hardware because you don't have PCI slots. You can't install most of these products for example in an iMac.
So what's the point as you don't need any of that...... You have excellent professional Music videos and even MAJOR release movies that were edited on a Macbook Pro laptop.
You don't need all of that to make it happen.
