You might have a warranty issue buying through Amazon. I'm not saying you will, but who knows? I know that if you buy from Google, either the phone works during the covered period, they get it working, or they replace the phone. (I had 4 replacements sent to me for one problem - when we finally fixed the original problem, they had no issue with having sent me 4 phones that were returned to them. [The last one was just refused - I never touched it, the carrier just scanned it as "refused".])
(Google's repair policy is one reason I'm sticking with Google.)
