The guy only forgot to mention there is also a 256 GB version being sold, not just the 64 GB model.
As for LTE it seems it will only be released in the future, not right now, or by some specific stores. BH said it's not available for them.
Also, didn't Samsung claim the battery could last 16 hours?
The above video shows:
Battery Drain @ normal battery settings:
100%- 6:05pm at 1:10min
99%- 6:07pm at 2:36min
98%-6:13pm at 7:45min
Which seems to suggest 13.3 hours of battery life, or less, since depending of what we do it should drain faster. I hope someone tests this.
