Are we going to discuss this in circles? Is that what you want?Certainly, but many of the patents that do surface have become produced in their products years later.
Okay, maybe this particular patent will end up being part of an Apple product sometime before humans become extinct. Are you happy?
Look, there is no evidence of a touchscreen back sensor in any of the leaked prototype teardowns. It's not coming out next week.
If you're theorizing that it might be part of some device in the future at some point that no one can predict, that's fine, but it's not a particularly relevant discussion for the next-generation iPhone (i.e., the topic of this MacRumors forum thread).
