My main phone is running the Insider preview builds, so it's not exactly stable. I'll soon be picking up a second device specifically for work; as I need something reliable, rather than fancy, I was thinking a low-end phone like the 735. My question is, should I create a second Microsoft account to run the phone on? Or will it be fine using the same account that my main phone uses? What kinds of issues could I run into with multiple phones using the same account?
