It is the sense of having, "one device that can do everything," which sold me on the SP3 above all other options. Funny thing is that I honestly don't use the pen that often and avoid it religiously, typing instead unless I have to. However, having it there WHEN I need it is HUGE. I just can't stand when I feel a piece of technology limits me in some way. I call it, "I wish it did this" syndrome. That's the great win for the SP3. I never find myself saying, "I wish it did this..."
My Note 3, alas is sad and lonesome as well. It is now relegated to making phone calls and sending texts.
