I really liked my Note 10.1 2014 edition ...... and then I tried the Pro 12.2. For my uses, while it takes a bit to get used to the size of the 12.2, this tablet makes note taking at University classes simply amazing. e-book open in Mantano Reader, and Lecture Notes with audio recordings going at all times. Plenty of room to write in LectureNotes and still easily read the textbook. For me, this was not possible on the 10.1.
I love the S-Pen, and can't imagine buying a tablet which does not have one. The S-Pen raises the Note series far above the rest IMO. Just root the thing once you are sure you plan to keep it so you can get rid of the apps you don't want / use.
