I had questions in my mind about returns even after reading moto's return policy. They only explicitly said if you don't like color etc you can return in 14 days and order a new one as an example and I think they said you can only do that once. I don't remember if it said when 14 days starts - assume the day you sign for it. Does 14 days end the day you drop it off with fedex?
What happens if it's defective? What happens if you get several in a row that are defective? Add up shipping times back and forth you don't get much chance of getting a working one in 14 days based on my track record with phones (yeah I just had to rant about it again). It's easier to have a brick and mortar to exchange it at except if you run into rude sales staff. And then if you ship it back you have to reactivate your old phone and wait for new one.
I'm still tempted by idea of doing moto maker when it comes to verizon to get a 32GB but I worry about the defective unit scenario.
