And no one will get confused ?
How many uses accidentally touch their track-pad invoking some command with "tap to click" on currently?
This only makes it worse with force touch..... now u have the added ability of making sure if u do touch to "make sure u only touch either lightly or press heavenly"..
I anticipate... all sorts of things will happen, depending on what app your in, and it will be so frustrating that while on the surface, looks cool, it will really get under the users skin....
I hope this is implemented ONLY when u enable "tap to click" and not forced upon uses, as that will really look ugly.
Basically, I know Apple really wants to eliminate the "two finger tap" for right click here into a "smart" "how much pressure can we apply to achieve the same thing" kind of issue..... but it will only cause allot of headaches in the end.
As for implementing this on iOS.... well....... (switch to Android now)

You'll be glad you did.
There is only so far you can take it.
(What is wrong with that picture) ... Not on a laptop ...... It's basically saying "users don't want touch screens, so drawing on something that is NOT a screen looks way better" I would keep looking to see if this darn pen works, since nothing is appearing on my trackpad.
