You mentioned you wanted to do film. Pro Tools is the industry standard. If a professional posting house is mixing or recording, it will be done in Pro Tools. There will be exceptions, but what I will say is that both the West USA movie industries in LA and Vancouver are Pro Tools exclusive. Nuendo is the little bro of the industry. I cant say much on Nuendo, I have only used it rarely.
Now with PT9 working with any interface, its like any other DAW that you can use with any hardware now. This almost makes it a no-brainer for anyone - but this perspective is usually shared with other PT users as opposed to non-PT users.
The end to my rant: If you are going to own your own business for local audio editing, mixing, post production for commercials etc. and have everything in house - use whatever you want. If you want to be in the industry as a work for hire - or as an editor for movies etc. use Pro Tools. Knowing Pro Tools is like knowing the basics for this industry - but its not an end all either. Most people say that if you know 1 DAW, you know them all. I find it to be true, its just there is a learning curve to any program - many people know how to use them, but who can work the fastest and most efficiently is a different story.
In terms of whats being taught educationally - both my Bachelors in Music Production and Post Graduate in Sound Design for Film and Games were taught in Pro Tools. Logic was next. Logic is good for music composition. I havent found much use for it anywhere else, however it does come with timecode and frame editing right out of the box, which is something you need to pay for with PT.
On other programs mentioned:
I used Wavelab to master albums and print CD's with the corresponding metadata (tags, song spacing, etc). And I used SoundForge to do small audio tasks if it was the program available. Wavelab is a fine program, and I wouldnt talk smack about it either, now SoundForge on the other hand...
Note: I am not too much of a fan of anything running on Windows, as the possibility of a crash (that you cannot force quit) upon DSP/CPU freak out is slightly higher than on a Mac. This statement is strictly my opinion based on my own experience and observation. Do not quote me on this or your computer will explode...
