Did you read this at the end:
Should You Buy It
Nope. The curved screen on the Note Edge can surprisingly useful, and way less of a random gimmick than any curved-screen phone that's come before. But! It's not useful enough to be worth the extra $100 you can expect to pay for it. Besides, it's not worth the drawbacks; You lose compatibility with the upcoming (and awesome) Gear VR, you sacrifice some precious battery life, and you'll hate yourself a little bit every time you try to put the phone to sleep.
If the Note Edge was the only new Note phone, this might be a tougher call, but since it's not, the decision is easy. The Galaxy Note Edge is not a total disaster by any means, but you should definitely just get the Galaxy Note 4 instead, and maybe use some of the money you save to buy a bedside alarm clock and a book of conversation starters.
It is not worth the extra $100 just for the curved edge. But still I think its cool to have and is somewhat useful
