> You don't get a demo of a movie when you buy it

They're called "trailers".

And in software, it's called "screenshots."

If trailers are to films as screenshots are to software, then demos are to software as what exactly are to films?

I think your argument is defunct, and I don't think it's bad to expect a demo, no matter how expensive or inexpensive a bit of software may be.
