Another day, another Apple patent. But this one might be interesting, because it suggests that Apple continues to work on something a lot of people seem to want — whether they should or not.
The patent points to the use of piezoelectric structures to provide haptic feedback for future Macs. The idea is that we could have things vibrate, basically, and while we already have a trackpad that doesn't move but vibrates to simulate a click, this patent appears to show a new way of making that happen.
