True, there's no large screen or additional UI customization methods, but it remains sufficient. The scary part is that iOS Google apps are acceptable enough to where I am not terribly missing Android as bad as I expected...and I could be open to selling my S3.
With 64GB, I'm more excited to have my entire iTunes audio library with me instead of a few HD videos. For that, I'm fine with Netflix or even hauling my 15inch MacBook Pro for tethering.
Even though I'm open to trying the Moto X for it's accommodating form factor, I worry about Google Now functions in comparison to Siri. From past experience with that in addition to S Voice, Siri simply feels more "human" and overwhelmingly intuitive...especially when combined with the smooth look and performance of iOS.
