It may not be a question of what will it DO, but what will it do BETTER. You're a stronger man than me if you can give into that reasoning. Haha! My Note 4 works alright as well, but I'm ready to ditch Sammy and have a new toy. Even though there are things this one does that my Sammy doesn't, just because of the different OEM, I definitely don't NEED a new phone, but I fully believe I'll be more satisfied with this one for longer, especially since I swore my next device would be more stock android BEFORE I got sucked into the Note 4.
However, as I've said in this thread, I intend on buying the 64GB version just to make sure this one lasts me. This one will have to be my device for at least 2 years. Now that I'm married with a stepson, I can't afford to swap phones like I used to and still pay full price for them, so this is my last hurrah of jumping much sooner than I NEED to. Haha
