Understand, but then you have to expend more fuel to overcome angular momentum if you need to change attitude. Which they do right before landing.

Elon Musk on Twitter:
"Looks like Falcon landed fine, but excess lateral velocity caused it to tip over post landing"

Not 100% successful, but definitely a step in the right direction.
Btw, I've put a wiki as the second post in this thread SpaceX plans ocean platform landing .
Would be great if folks can help keep it updated with info the various landing attempts.

Musk said (copy of tweet to the right of your post) that video will be posted in a few days.

This looks much better than last time. Hopefully the ship did not suffer a lot of damage from the impact.

Seems like it landed but fell over because it still had horizontal velocity (looks like it was still adjusting the position right up to the last second of landing). The wind probably had a lot to do with it.

Which means when the landing is entirely successful, they'll be able to land that puppy on any pinhead, anywhere in the world, under any set of conditions.
I'm not a rocket scientist but I think they need to program it to reach 0 velocity about 10 feet above the drone ship to correct for horizontal motion. It needs to pause there and stabilize itself before dropping the 10 feet onto the ship. My experience comes from playing lots of lunar lander when I was young.
In this latest picture and the previous near miss you can see the booster coming in at a sharp angle maneuvering to reach its targeted destination. The thing we don't know is whether there is any fuel left at all. If there is some then it could be used to stop the horizontal motion.
Interesting that the booster has burn marks in the picture. The ocean seems pretty smooth too.

I'm sure that they learn a lot with each launch. The fact that the Falcoln 9 has achieved every primary objective in every launch is astounding.

just raise the landing platform with hydraulics and make it move to "catch" the rocket. 
And/or move it to balance out any weather/wind inflicted movement of the drone ship.

Elon posted video on twitter. Up to the point of tipping over.

Maybe it's just me but looks like the software isn't very balanced. And thrusters at top of rocket seem to be turned off at the end.
