No, a table gives no feedback whatsoever in the manner that he's referring to at least. When you hit a key on a keyboard the key sinks into the board, you have a positive 'strike'. If you miss the key slightly then it feels different and you'll know before the wrong letter appears - this is what is meant by a feedback loop.

That's off-topic. We're talking about touchscreen keyboards, as is very clear in my post, and we won't pretend their keys sink.
