Put iOS on the S8 and make turn the Bixby button into a Siri button I would be lining up right now. Maybe put the camera at the top left and make the fingerprint reader the Apple logo that lights up I would sell a kidney.
And I'm the complete opposite. If this ran iOS, I'd just have stuck with my 7 Plus. Part of the reason for switching to the S8+ for me is that it seems a Samsung has gotten better about their software and Apple has gotten worse.
