Sideload updated it from the link on droid-life, since my OTA download failed like nearly everyone else's.
It's nice! The scrolling for everything is definitely smoother now. Project Butter worked out for our phones!
Other finds, there are some Moto apps that aren't there anymore. No more My Files, My Music, My etc. It seems to been consolidated into Motocast? Weird little thing, the "Dual Core Technology" is gone from the boot logo also. Other than some very subtle image changes, the homescreen GUI looks unchanged. I'm running Nova on top, so I'm not saying much other than it's BUTTER!
I can't report much on battery life, I flashed at 50% so I'm going to FoxKat it tonight. I also didn't FDR, so I'll see if there are any issues there. I also kept root using VooDoo Rootkeeper, no issues there.
Overall, HUGE improvement so far.
