Agreed. Lip reading via the camera would be much nicer to use (although probably an order of magnitude more difficult). :)
And speech isn't weird in the same way that touch-screens felt weird for some of us at first. Because touching the screen of your gadget does not annoy other people.
Also, did anybody notice how awful speech recognition is for non-Americans? And they just got in the habit of internationalizing things properly, now we're going back to square one, except for the fact that learning to pronounce things with an American accent is much harder than writing words in English, so devices will annoy the heck out of us non-Americans, even if we know English.
