Amazon's new lineup of tablets don't just differ from the original Kindle Fire in their hardware. Like last year's cheapest Kindle e-reader, all three new models — that's the Fire, the HD 7, and the HD 8.9 — will display Amazon's "Special Offers" promotions and advertisements on their lock screens. Unlike the low-end Kindle, however, Amazon isn't offering the devices in more expensive, ad-free models, nor is it making mention of any way to opt out for a fee.

Considering the aggressive pricing of the new Fires we imagine many people won't mind, especially as the offers include deals such as a $5 credit for Amazon's movie and music services. Not everyone is going to be comfortable with paying for devices that advertise at you, on the other hand, so it's notable that Amazon doesn't seem to be giving customers the option.
