Does anyone know what the best program to use for 2d/3d animation is. i.e. ease of use for a beginner but advance features for when i learn to use it, i want to start making short animations, 5 mins to start then eventually full movies, any suggestions? Also is a mac or pc the best medium to work on. I'm gonna be buying another new unit soon always used pc's, but if macs are the way to go with this sort of thing i'll do that.
