I did the manual update and I LOVE it. 100 times smoother (I know, that is hard to believe because it was very smooth before Jelly Bean). I love the new little features it has, especially Google now...If you are like me and wish the Motorola clock was included, look no further. Follow this link
[APP] Motorola Razr M Launcher / Clock Widgetand install the Weather, rings, and homescreen zip files. Once you use launch the new homescreen, you can then select the rings clock as a widget. This was unable to work previously because the stock weather motorola app wasn't able to uninstall, so you couldn't sync the weather....well now you can!!! Overall, if you are one of the many that didn't get your hands on the OTA update and you are debating on flashing it yourself, I would say go for it and don't look back...
