Oh yes, I posted on this a few weeks ago, but apparently few people have trouble with the touch ID. Mine works sporadically. I've scanned two fingers. The first one works some of the time; the second one only very occasionally. When I reset the fingers, go through the process again, both will work well for an hour or two and then gradually work less reliably. I haven't gone back to the Apple store with the problem because I know that the Genius will probably work me through rescanning the fingerprints, and show me that the Touch ID works well, and it will work well for a couple of hours.
