Depends on your style and what you shoot.
For portraits, weddings, etc. it does not matter too much. Most run of the mill strobes will have duration short enough to effectively freeze motion. With skateboarders, dancers, etc. controlling the flash duration can be critical to getting the look you want though.
Even with "moving" objects, there are ways to diminish the "effective" motion that the camera sees. Something coming straight toward you, or further from your camera, or seen using a wider lens will show less apparent motion.
But sometimes you just need short duration. Liquid pours, dancers in mid air, etc. If you only need that rarely you can rent when you do. Or **try** to get by with speedlights instead of strobes. Speedlights can have very short durations. Obviously that only works with smaller sets, etc.
Reducing the power on a strobe usually gives you shorter durations. But of course you can also run out of power - there are some tricks to get around that.
There are a couple of examples and a decent discussion in this brochure from Broncolor, starting on page 8:

Brent Ward has been using short duration to do liquid pours lately. Not sure how much he has on his web site. Do a search here to find a link.
Are you buying, already own, just curious? What are you using?
Best,

Mainly just curious. I've just really not run into situations yet where I find I actually need short duration. I have alien bee stuff and am in the process of buying Dynalite gear.
