This feels like it's veering a bit into app design territory.  It will
 always be up to application developers to map inputs in a way that 
makes sense for their apps - that's true whether default pressure is 
0, .5, or 1.

We should pick a default that makes it easy for users to switch 
between {mouse, pen, touch} with a consistent experience.  .5 wasn't 
my decision, but since that's pretty close to the amount of pressure I
 expect stylus users to apply in average conditions, it seems 

Hopefully, we can design a system that does the right thing on the 
pointers that developers might not think about, either by picking 
reasonable defaults or by forcing them to think about all kinds of 
pointers through both API design and education.  Hence, I see value in
 making the experience similar across pointers, but inventing the 
algorithm for different brush types in a painting app feels a little
