Agree. All winds should be three digits. Always.
Short, embarrassing story: The Garmin G1000 omits the leading zero as well. I was flying with an ATP friend in the right seat and he pulled up a field METAR on the G1000. We both saw the two-digit wind number and somehow mentally added a zero at the end. Kind of like taking it as a runway number. We landed uneventfully with a moderate tailwind. Used lots of runway though.
Pilot error? Of course. But I also consider it to be a UI fault.
