I have always used MS but two of my (grown up) children keep telling me I should switch to Apple. One is in film and one is in design and I get the impression that Apple,in both those fields, is ubiquitous.
However my computing skills are so dire that it would make no difference to me..
Its like saying, I need a camera, what Canon model do I get
Years ago Mac was what you needed as it did perform better, PCs are now the same so there is no real need. It comes down to the software and I think in movie making the software is better/more affordable on OSX. AS with anything though it takes years and years for beliefs and sayings to change.
