It's been rumored for months, but it's finally here: Samsung has unveiled its new flagship smartphone, the Galaxy S6. But this time it's accompanied by a cooler, better-looking brother — the Galaxy S6 Edge — which features an eye-catching design with a screen that curves around both sides.

Yes, we've seen this before, sort of: The Galaxy S6 Edge borrows heavily from the Galaxy Note Edge, which came out last fall and had a curve on just one side. But where the Note had a versatile side screen that doubled as an app launcher, news scroll and occasional ruler, the S6 version is more limited: The curves are mainly a design ornament, and there are no "panels" to swipe through.

So what good is it? Besides giving you something to brag about to your friends, the S6 Edge still has the side clock and news scroll, although you can only call them up in standby mode. You can also instantly call up a list of recent contacts with a swipe of your thumb, and if the phone is face-down, the sides of the phone will light up when someone calls you.
