The Nexus S has the same hotness the Epic 4G does - the 4 buttons below the screen are totally invisible when the backlight is off. That's SOOOOOO cool.
Hopefully they actually stay on for more than like 0.7 seconds. I have a Captivate, which I totally love, and it does the hidden button thing as well. But for some reason, Samsung thought that having the buttons turn off almost instantaneously was a good idea. You end up having to hit the bottom of the screen to
"wake up" the buttons, then tap again to actually have the button register a press. It can get annoying. Hopefully with the Nexus S, the buttons just stay on as long as the screen is active. I've seen some videos of the phone, and it seems they did actually fix it like this, so that is good.
And yes, I fully agree. The Nexus S is a kickass looking phone. I love my Captivate so much, but I just
HATE all the AT&T crapware, and Samsung's Touch Wiz ui is not much better. Getting the Galaxy S hardware with no fluff, just straight Android would be amazing. It would eliminate many of the tweaks and hacks you have to do to the normal Galaxy S phones to make them useful. I really want one, but I'm going to wait and see if they come out with either an AT&T versions so I can just swap my SIM, or a Verizon version and I'll change carriers.
