Yes, but it's equally ludicrous to say that the stopwatch "didn't give the visual feedback". It started incrementing those huge numbers, didn't it?
That is not the visual feedback being discussed. Buttons should act identically across a platform. There is no compelling reason for a difference.
I did not comment on the implementation. I said, in effect, that an animation would affect the perception of the start/stop times and using one would therefore be a bad idea in this case.
