Yeah, there are some nice shots in that gallery that play well with the excessive sharpening, but if these are untouched photos I agree that there's way too much sharpening happening. And I'm really tired of the argument that megapixels aren't important. Yes, the lens and sensor are obviously bigger image quality factors, but more megapixels = larger images, and larger images offer greater editing flexibility and will be more future-proof for displaying online as screen resolutions continue to increase. 12mp is fine, but it still feels like a step backwards for Samsung from 16.
As far as the phone is concerned, I think it looks really nice. Watching the "first look" video someone linked, the back doesn't seem to be the greasy fingerprint magnet the S6 models were (I wasn't paying attention to the S7 release). I'm still happy with iPhone, though, and I'm not tempted to switch. iOS is fast, stable, secure, offers a top quality selection of apps, and I think its a great mobile operating system. If you like Android, more power to ya! The competition benefits us all, and at the end of the day they're just smartphones!
It'll be interesting to see what Apple has in store for the 7. A lot people around here talk like it's already been released, but all we have are rumors and I'm sure Apple still has some suprises up its sleeve.
