Definitely in the same boat. When I started reading through this rare opportunity for legitimate meta discussion I was about to advertise the missing vote direction indication on the unvote button. Because it's so easy to hit the wrong direction on mobile and that would be an elegant way to fix it.

But now I think that even this might be more feature than bug: knowing that there is a chance that it might have been just clumsy upvoters makes it easier to do the right thing when getting downvoted.
