Hands down the best design of any smartphone of 2015.
The S6 Edge looks like a really great device with really good reviews. The only drawback I see with this phone is the battery life and the software. The battery looks alright but if you're used to big batteries, this phone will be weird for you. The software is running Android (you probably knew) but it's skinned by Samsung's TouchWiz... If you don't know how bad TouchWiz is, it's pretty dang bad haha. I don't have personal experience with using a TouchWiz skinned Android phone but my mother has, and she says it's really bad. So it really depends on how the user likes the software. If the user doesn't, the phone is pretty much a bust for them. But other than that, it looks really great.
