I currently have a Nexus 6P and I'm not sure how I feel about the trend of having curved screens. It doesn't seem to add much utility and comes with some significant drawbacks like a more easily broken screen. I'm also not sure how well you can get those tempered glass screen protectors to work. I would be somewhat surprised if Apple goes down that route. If they do then I'm sure the curved screen fad will be taken to a whole new level and I doubt I'll be able to buy a non-curved screen phone for much longer.

I'm sure having smaller bezels, especially on the top and bottom, will be a welcome improvement though.

The samsung edge family has a real wow factor to it. On the street they really stand out among the generic rectangle-with-rounded-corner design everyone else are holding.

I don't think it's the most ergonomic design, but it really looks cool. And let's face it, that's as important to many,

I agree. My experience with the curved Galaxy phones is limited to in store demos so I don't know how valid my ergonomic concerns are if I used the phone daily and got accustomed to it. I do agree they look very nice.

The Xiaomi Mi Mix is another phone with tiny/nonexistent bezels that looks great but has ergonomics that concern me.

Stand out? The only thing I see are slightly rounded edged of the screen. And that took me a close look.

That small detail really stands out when all other phones look so generic.

I don't think they'll get rid of the physical (or at least in the case of the iPhone 7 kind-of-physical) button. It's part of their design language. If they do it would have to be a prominent, always on part of the UI.

That is of course unless they completely redesign the phone.

Still wont be getting one though

technically the iphone 7's don't have physical home buttons...they're part of the screen and the "click" feeling you get is actually haptic feedback. try clicking the button when the phone is off and you'll find it does nothing (which is quite sad feeling, actually)
