Taking notes is super easy with OneNote and the pen. I wish I had it while I was still in the university... Haha. But now I use it for drawing, taking some notes here and there. A lot of times I write on screen shots to be able to better explain what I want people to do. My brother doesn't understand anything about technology, so I often take screenshots and circle where he needs to press. I love my pen!
I got my SP4 yesterday, and coming from the SP2, there is a huge difference in pen quality... Haha. I feel like I can paint like Bob Ross! xD
