I have had 2 Galaxy Notes (original and Note 3) that had built in pens. They were cool to show to other people but I never used them other than that for two reasons. Firstly my handwriting is atrocious. I am a fast typist so keyboards have always worked better for me. And I am not really artistic so drawing pictures on a tablet isn't something good for me. Now I have the Surface Pro 3 and another pen. I didn't even bother to stick the tab on the keyboard to hold the pen and I just put the pen in a drawer. Am I missing something. Is there some great use for a pen on the Surface Pro 3 that would make it worth taking along when I go out?
