The Supernote is a superb instrument. The Push-Up pen is a big deal though. The standard pen worked fine but the cap consistently separated from the pen costing time to look for it. The Push-Up pen takes care of that. Perhaps, that should be the standard pen.
This is so much better than the pen I had before this design. The pen fell from the cap, which I eventually lost, leaving it unprotected. I never have to worry about this again, thanks to the new design!
