All Kindle Fire HD models ad-supported, but only in the US
Amazon announced the Kindle Fire HD with great fanfare, but forgot to mention all models have ads. The ads are on the lock-screen and home screen all the time, and cannot be turned off. At least for those of us in the US (and UK it turns out).
The new Kindle Fire HD tablets from Amazon have good hardware and software technology inside that belies the low pricing. It turns out that pricing is low due to the inclusion of ads on the Fire HD lock screen and home screen.
The ads on the new Kindle Fire HD tablets will be on the lock screen that is displayed every time you turn the device on. These ads will include "sponsored screen savers" according to Amazon. The lock screen disappears as soon as you unlock the display so this may not be an issue with most users.
The other ads will be on the lower left corner of the home screen. Amazon insists they will not interfere with the normal use of the tablet, but that will be up to each user. It cannot be turned off so it's there to stay.
Amazon took this ad-supported route no doubt to keep the prices of the Kindle Fire HD as low as possible so it may be an acceptable trade-off for most. At least that's the case in the US, as the info screen above details.
It turns out the ads will only "be available in the US". Folks outside the US won't get the ads which is a plus to most folks. Unless it causes the Kindle Fire HD to be priced higher than it would be with ads, in which case buyers will paying for lack of the feature.
Update: Amazon has confirmed to CNET UK that Kindle Fire HD tablets in the UK will also enjoy the ads.
Update 2: Amazon is now stating that no-ad options will be available for the Kindle Fire HD for $15.
