I believe force-touch (assuming it's coming) is in the unique position of being the first killer feature (since multi-touch) the iPhone has introduced that other smartphone makers will look bad if they copy it. Siri was an app after all, and Touch ID (while being the most reliable) was not the first fingerprint scanner. I really hope Apple patents this feature well! There could be some really neat uses for it. I would want it for dismissing all notifications, closing all apps, and opening a tab in the background. What do you guys think?
