This is a cautionary tale. Jason Howell, Android geek, used his Google Voice number to authenticate his Google account. Problem is, that Google Voice is on the other side of Google sign in. So, if the Verification code is sent to a Google Voice number instead of a cell phone, you can't get to it for the code. Ouch. Happy to see that even Google experts can be trapped sometimes by the vagaries of tech. Notice that, like the FutureLawyer, Jason is playing with the ASUS Chrome OS Flip that now gets Android apps. Watch and learn, grasshoppers.
