The best thing that ever happened to N-trig? Microsoft buying them.
Their previous products were a disaster prior to the Surface Pro 3 Pen. Now this pen is the premier pen. I was very sad to learn when the Surface Pro 3 came out that it was switching from Wacom to N-trig. My previous experience with N-trg on the HP Slate and Dell Latitude ST devices were a complete and utter fail. Their support was worse.
Future is looking bright for the Surface line and N-trig.
