Super meat boy has a really tight platforming gameplay though, a controller that does not react rapidly and appropriately would make it impossible to play at the highest level (watch some of the speed runs). I.E. If there was latency from the controller, or if the pads were not precise those details would be reflected in playing meatboy. Given the creator didn't have a problem with those aspects is a good thing - I'm not sure what the point of your post was precisely. But given all games to test controller latency and relative feel - meatboy is a great test game.
