With the Galaxy Note 9, Samsung ticked off a lot of boxes that Note fans have been wanting for years. Huge 4,000 mAh battery? Check. An S Pen that can be used as a remote control? Yep. Large storage configurations? You betcha.
Looking specifically at that last point, Samsung's selling the phone with two storage makeups — 128GB and 512GB.
Both should be more than enough for most people, and looking through the AC forums, it appears that folks are pretty much split down the middle in regards to which version they're buying.
