Kit Kat NOW!!

Nope.. It is taking FOREVER to download. I am on WiFi and it is still only at 15%. I am going to try to shut off the cell data and only use WiFi.

For reasons I can't figure out, mine won't install 4.4...:(

From a Sprint Moto X
 
I just downloaded the OTA file from XDA developers, followed Jcase's instructions for SlapMyMoto exactly to preserve root, and ran the update on both my Maxx and my girlfriend's Mini. Both are happily running with rooted 4.4!
 
Things seem to be fine. I've tried to switch from Dalvik runtime to ART but it won't stick after reboot. I understand that's because I'm running Xposed framework.
