Amazon already effectively offers free trials for Kindles and Kindle Fires, but until now they charged customers and then refunded the purchase price when the Kindle was returned. Amazon also usually deducts a return shipping fee when any non-defective device is returned, but they're not doing that in this case.
Do you think this means Amazon is getting a little too eager to sell their tablets?
In a word, no.
This is not a sign of desperation until and unless the offer is opened up to everyone. One offer here and another offer there is a marketing ploy, not a sign that Amazon's hardware sales are in trouble.
