So type on the table?

Seriously, wouldn't that be the same amount of feedback as a touchscreen keyboard? Flat, and you get the wrong letter when you miss?

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.

With an on-screen keyboard, you get visual feedback seeing your fingers land relative to the keys, even if you don't give tactile feedback. With this, all you see is whether you got the letter right.
