I agree with Mark.  When you look at the list of software used to make Kung Fu Panda, you will see that pro shops use lots packages to get the job done.  Hobbyists don't spend 100,000 budgets to make a movie and instead, invest a lot of time and personal cash and ownership into one package.

The result is very real and significant attachment, protection, and ownership which you ares. seeing.
