I have some thoughts about this:
1) ANYONE who bought an S4 instead of an HTC One (save for VZ customers) is a hypebeast and really doesn't care, or at least shouldn't.
2) ANYONE who bought an S4 instead of waiting until today to abso-noodl-utely, without a doubt, bet your life savings, sure as Sherlock that neither Motorola, nor any Nexus device would rear its mythical head BEFORE making a hasty decision is a hypebeast and really doesn't care, or at least shouldn't.
3) The price is fair for an unsubsidized phone considering it's still a mainstream phone with lots of buzz. Anything less would undercut Samsung (bad). Instead, you get a standard price for a phone with beast specs (good).
I'm pretty sure my GNex was more than that ($700 for CDMA) when it finally released on VZ. It's arguably an enhanced S2 that fell into obscurity, thanks to the Big Red Baby. A brand new device with AOSP and no bloat or skin running those specs within 2 months of its release? And you're arguing over $650? Minus the arrival of the XFON or a decent CDMA Nexus (unltd. data like a champ), the only thing that would have been better is an HTC One with AOSP.
I would also take an Apple-branded Nexus just for the sake of irony. I wouldn't want it, mind you. I'd simply want to see if you really CAN turn lead into gold.
