There you go...
Indoor concerts, indoor sports, anything indoors where you need to stop subject motion, the extra stop can be a make or break type of thing.
For instance, I was shooting a concert late last year, was at ISO 3200 (didn't want to go ISO6400 on my 1DMKIII), shutter speed of 1/160 to stop some action, and f2 on my 200L. That extra stop sure came in handy.
I shot some hockey earlier this year for someone. I had the 1DMKIII + 70-200 f2.8 IS. Was at ISO3200 (Again, didn't want to use 6400), 1/160, f2.8. With an f4 lens, I would have either had to shoot ISO6400, or at 1/80, which would be too slow.

I constantly see people talking about 2.8 like it's a godsend. In real world shooting, if you can't get an image with f4, how likely is it that it will be a great shot at f2.8?Maybe I'm just not in the correct conditions to recognize it.
I feel that I'd need a fast prime to capture the images in dark situations that I can't with my other lenses.
this is not taking into account DOF issues, just being able to get the shutter speed to get the shot.
