Off Topic, but I have to say I have elevated hopes for the V20 and Pixel. V20 screen bleeding doesn't look great, but IMO we're at the point where even the "worst" high end device is going to be an impressive one.
Trade-offs; V20 has removable battery, SD slot (!!) and awesome analog audio (big FLAC fan, here). Pixel lacks those three, but has the power and volume buttons in standard spots, not sure if the LG setup is something I can get used to.
Anyway, either device will have a better camera and features than the Droid Z, which is a great device if you need a rugged phone and the mods are beneficial (personally the mods are useless, the Hasselblad camera is garbage, and the phone is just too darn long or something. I can't comfortably hold it!)
