Well, I'd love to get a 200F2 prime, but it's expensive and much heavier than a 70-200 anyway. I find myself using 200 a lot, and not just for distance, but compression too.
Kitty summed it up perfect, but I do like using primes when I have the time and in certain situations I think they're perfect. During a wedding, the bride getting ready is the perfect time to use them. In fact, I leave the zooms in the bag and leave my primes on a surface nearby. I know I can switch focal length with a turn of a knob w/ my zooms, but primes force me to slow down, even a little bit, to think of the composition a little more and as crazy as a wedding day is, bridal prep is the least hectic part of the day. Since I have two cameras, I don't switch out that much. I also feel shallow DOF can make some photos exceptional.
However, when it comes to the ceremony and reception, the 70-200 is stuck like glue and either a 24-70 or a wide prime like the 24 or 35. If I'm by myself w/ no second, the 70-200 and 24-70 without a doubt.
