I beg to differ. I believe that the real issue here is one of third party apps. When moto releases software they only test its use with the apps they or verizon approves, and even then there are bugs with their pre approved apps. In any case, Moto or VZW can't test every possible sinario with the thousands of apps available for download. And yes each person's phone operates differently and we all have different stuff installed, so of course when you load new software against unknown situations, it will most likely cause problems.
I'm sure that many people out there with device issues, if they deleted all the 3rd party apps they installed and removed non approved tweaks, reset the device, and run it how it came, there would be minimal issues, which proves the point of the more you begin to install, the higher the rate of issues you receive.
