Oh yeah, it did land right on target.
Wee-eelll, to be exact, 210 feet off target, but that's accurate enough.
It was, according to the report, "right on the money".
EDIT:
According to the article, the instruments also worked perfectly, and better than expected in some cases.
"'It could be water, it could be methane, it could be hydrocarbons or organics,' Colaprete said during a pre-impact briefing. 'From a scientific standpoint, this is incredibly important. Whatever the moon has collected over the last 3.5 billion years in terms of water, organics, materials from comets, asteroids, the sun, could be trapped in these pockets on the moon. It's a time capsule, it's a window into the past of the entire inner solar system, of Earth.'
Finding ice on the moon could be critical to future exploration or even colonization. With unlimited solar power, ice can be converted into water, oxygen, and hydrogen rocket fuel. Finding ice on the moon also would raise the possibility of similar deposits in similar environments across the solar system."
