Personally, I almost always do. You're right one of the big problems is that people treat estimates as commitments and they're not that. They're called estimates because it's an estimate not a certainty. That isn't an issue with the estimates themselves though. It's a culture issue. Saying estimates are useless and I'm not going to do them because my company treats them as commitments is throwing the baby out with the bathwater, IMO.
