Hi and welcome to Android Forums!
I would LOVE a 64GB Note 3... however, it has become clear to me that such a device is not available for me (on Verizon) and probably won't be. Therefore, I improvised: a Samsung Professional Series 64GB Class 10 microSD card
for under $1 a GB shipped at Amazon! Class 10 speed is nearly as fast as onboard speed (maybe benchmarks can tell the difference... I'm not a benchmark), and will very likely be cheaper. Plus, it's removable.
In essence, I will have a 96GB phone for less than the price of a 64GB phone. And all things considered, that's a pretty good deal to me
