The size is the thing for the 5x. I want a phone not a surfboard in my pocket.
The updates & fingerprint sensor are great, too. And I love the Pure Android (get the shirt...) experience that Google delivers (and Moto used to...facepalm).
I want a phone with a light, nimble software experience with no bloat. That is ultimately #1 for me, which is why I've been romming since my old Droid Eris days.
Love the site & the podcast, too. Been listening since the episode count was in the single-digits.
