The problem I am seeing with propriatory software, is that I do not have the freedom to use them the way I wish.
My point in case is Zbrush… I love this application, and I cannot do without it…
But I cannot use it in linux… and to re-install it after a hard disk crash takes an Email from me, and a weekday for them to respond (saturday and sunday you are screwed)
Yet, with my trusty little GIMP, I can have installed anywhere!
If my system fails, i can even run it from a live CD, while linux installs itself.
With Zbrush I am stuck using windows or MAC osx…
guess my point is, dont get too stuck in propriatory software … you may become dependent, and always have to bend to their rules and demands, to be able to make your artwork.
GIMP + Blender gives me lots of freedom about where I use the software, and when, and who I can share it with.
