(1) Beautiful display. Vibrant colors & sharp !
(2) Love Stay Stay !
(3) The S-pen is fabulous. So smooth to write. Much much better than the Note 1 pen.
(4) Have been using the Note 2 all day long and much of the time connected to the PC, as tranfering all my files to it. So, haven't checked out the battery yet.
(5) Google Now looks great.
