Hey Everyone!
Thanks for all the feedback!
As some of you have already noticed, on July 14th, 2016, we released an update to the Surface Touch Driver that should significantly improve the pen tapering and pressure experience that this thread talks about.
For more information on the 7/14 update, you can go here.
If you experience any difficulty downloading or installing updates, please check the Troubles installing Surface and Windows updates article for assistance.
Thanks!
Zachary
