When it comes to smartphones, convenience is paramount. The whole existence of the category is centered around doing things quickly and easily, while you’re on the go. So anything that adds to that — anything that cuts down the number of steps in performing a task — is a win.
That’s why I’m a huge fan of the Galaxy Note Edge. When Samsung first unveiled the phone, it turned a lot of heads. The sleek edge panel, which adds a curved vertical screen along one side, was something new and unique. But at the time it wasn’t clear if it was really practical, or just flash.
