from Note 1 till Note 3, i acquired all generations of note (now even have Note 3 Neo), but still did not really use the S-pen..  but there are times that it become handy to sketch sketch.. but, really, the s-pen accuracy improved a lot compared note 1 to note 3.. now its very accurate, can write small letters. it will be nice if such pen can become an essential feature of all smartphones.
