I guess they registered the serial number in Google Play when I purchased it there.
Yeah, Amazon does that with the Kindle. However, this can be a mixed blessing.
One Kindle user review said that his Kindle was delivered, second-day-air, no signature required, and arrived right on time. Unfortunately it was delivered to the wrong person, and that person immediately fired it up and downloaded $400 worth of eBooks.
My experience with Amazon's customer service leaves me in no doubt that Amazon will make it right, reverse the charges and send him a new, hopefully unregistered Kindle. But the whole thing is a bit bizarre.
