I think it's a good phone so far, but I have one minor gripe and one MAJOR gripe.
Minor: Physical home button takes some getting used to.
Major: Music sucks through even good quality headphones. Sound is thin with no bass, and Samsung is the only OEM that didn't bother to include any kind of EQ. Apparently Samsung thinks "professionals" don't like music... As somebody who LOVES music passionately, I might return this phone... Unless somebody wants to trade me straight up for a Rogers or unlocked 920. Color doesn't matter, and I don't care if it's carrier branded as long as I can use it on Bell in Canada. This rules out ATT devices unless you somehow managed to convince them to unlock it for you. I will pay to unlock as long as I know I can get the code. ATT is notoriously stingy on this one... PM me if you're interested.
Update: Figured I'd give a more complete review now that I've had a couple days with the device. (and no bites on the trade offer

)
The Good:
-Screen is GORGEOUS! Deep blacks, rich but not oversaturated colors, and text is pin-sharp!
-Battery life is fantastic. My HD7 had to sit on the charger so frequently that I wore out the micro USB port 16 months into my contract and couldn't get it to charge anymore. Even with all features on, AND new-toy syndrome, I haven't felt the need to head for an outlet before bedtime yet, and the battery hasn't been below 50% since I powered it on right out of the box.
-In hand feel is great. EASILY on par with the 920. I know it's still plastic with a fancy finish, but it feels premium, and the glass has a slight curve at the edges that would feel better if not for the bezel protruding past it.
-Call quality is loud and clear, and I get great signal even in traditionally weak areas of my commute.
-Data feels super fast. I haven't used speedtest.com or anything like that yet, but downloading a song from Xbox music takes but a few seconds, and there's no LTE in my area yet.
The Bad:
Music sound quality is pretty much my only valid gripe here, now that I'm getting used to the physical home button.
Update: I think Samsung may have responded with some firmware... I have my phone set to automatically receive updates, and I've gotten a couple, but in the last few days I've used my Sony ear buds quite a bit and it sounds better. A lot better. Still not what I was accustomed to with my HD7, but pretty good!
