The bit about the swappable pen tip picked my interest, cool feature! As an avid believer that pen input is the most flexible way to express your thought process, I find it a bit of a lost art though, people born in the new millennium just wont spend the time to learn to write cursive. I went through most of the Note generation from Samsung and the SPen is getting really close to the look and feel of writing on paper. There's a Google hand writing keyboard for Android that is really good, in fact I am writing this using it. Still, it looks like it will continue to be a niche functionality at best.
