I'm not going to claim that you didn't experience what you experienced, but I have NOT experienced any of those things. But are you referring to the Adonit Jot or the Adonit Jot Pro?
The Adonit Jot is $15 online at places like walmart.com. I have not experienced any skipping. "Pressing down harder" makes no sense since it is a capacitive stylus, pressure is not needed nor is it registered. Even if one were to stab the screen with it, the stylus would break well before the screen cracked.
Those $1 rubber or foam tip styli do a terrible job on the Surface.
Microsoft IS thinking and they were correct for not including a digitizer in the Surface RT/2. Many, many are using the capacitive touchscreen on the iPad with great success. Myself included. Where Microsoft may have been short sighted was in cheaping out on the resolution of the sensor array of capacitive touchscreen. The iPad (even the non-retina display models) appear to have a higher resolution sensors.
