Narrative:

Vectored to boi and then direct; 10 miles from localizer; slowed to 200 knots; and vectored to intercept 10R localizer. Flaps 10 and gear down approaching glideslope at 4000 MSL; intercepted the localizer and tailwind 20 plus knots. Speed crept up to 200-205 knots; initially from 190; and slowed to 180. Selected flaps 15 and continued to slow. At flaps 25 at 1000'; tower cleared a be-200 for takeoff on my runway as we passed 1000'! 10L had a small aircraft landing short final. Large thunderstorms were at the departure end of the runway with a low ceiling and a slow climbing king air in front of me. I elected to configure and land to avoid a mess at the end of the runway; had I chosen to go around. I landed on speed; configured; and exited at D intersection with no problems. I elected to land because a go-around closely behind a king air climbing and a low ceiling with thunderstorm and numerous small aircraft in the pattern would/could have been very dangerous and we were stable and on glideslope; although late configuring. The first officer and I discussed the issue quickly and we agreed to continue instead of going aroundapproach control could have told us there was a 20+K tailwind on final; while calm on the runway. Tower should not have cleared a takeoff in front of us when we were at 1000! It left us with few options! We were ready to go around until the king air took off.
