I am seeing a lot of people downplaying the new Note, i came in with the same mindset a couple of weeks ago, but honestly there are a lot of things that look really good to me.
Dex on Windows - that is a game changer to me, no one used Dex and for good reason, but this is something i will definitely use, controlling your phone from PC, having them run concurrently and seamlessly, this alone is a big step up.
The 3D scanner option seems really interesting and if done properly gives us the option to scan and 3d print objects better than before.
Video editing built in seems good and the upgrades made to video capturing
The auto cataloging your notes and having them indexed and searchable, or option to convert to text and export is huge
The Galaxy Link Play thing looks really promising, i hope.
These are things that i can remember that are pretty good upgrades.
I know no head phone jack, but let's face it, once you do go wireless it is a pain to go back and this is the way of the future, so get nice wireless earphones and get over it.
