It sucked for the following reasons: - too easy to accidentally touch while reaching top-row keys. - cannot be used by feel. - replaces existing keys, removing functionality. - turns off sometimes, so we have to tap once to wake it first. - some common actions used to be 1 key, are now two taps (volume, brightness). - does not always register my taps. No unambiguous indication that the tap was recognized.
