The charge is NOT drunk driving
It is "Driving While Impaired".
The question isn't whether you're unable to walk and have no judgement. The question is whether your reaction times are slowed to the point that with your usual driving habits, you will be unlikely to respond quickly enough if something unexpected happens. (Most accidents associated with alcohol are due to poor reaction time causing you to not react fast enough to, say, someone you didn't see crossing the street or the car in front of you stopping abruptly.)
Most people don't understand this, and so don't understand why DUI limits are set so low. They aren't set to the point where most people are drunk. They are set to where most people are intoxicated.
Cheers,

PS D'oh. I can't believe that I messed that one up. I was thinking the right thing, my fingers just didn't get the message. I swear. And no, I was not drunk posting...
