I love my Razr. I got this phone with the intention of trading it in for the GN when it arrived. But after having it for a few weeks, I have made my mind that I will be keeping this phone.
The build quality is great, just like the OGD. I could care less about the non-removable battery...I never took my battery out of my OGD.
As far as battery life, I have been using Juice Defender and I must say that it helps out a lot, especially when you customize your settings. I have not tried Smart Actions since Juice Defender works for me. I was able to go all day yesterday (9:00am - 12:00am) and battery life around 35% when plugged back in. This was with moderate use, including phone calls, few vids on youtube (on 3g), checking email, lots of texting, and streaming from gmusic. I purchased my phone from Costco, so I also will be receiving their accessory pack that they offered. It includes an external battery pack and I will use that in a "just in case" moment.
Overall, I am VERY PLEASED with phone.
