The way game input works compared to OS input is very _very_ different.
Games go through a more direct mode of user input (directX) whereas the OS has to take into account that where your clicking can do a million different things (basically games take -almost- exclusive use of your mouse/keyboard). This becomes even more problematic when it's in a drawing application and they're now running math over your input to figure out exactly what you meant.
I'm with you though. They really shouldn't have come this far with screwing up the latency on the pen again (this fixed it on the surface 2 after talking to gabe last time as well...)
