Battery Life: 6 Hours

I swear the Kindle Fire has a hard stop at six hours of continuous use. Regardless of the nature of my benchmarks, the Fire always dropped out after six hours of use. I ran our video playback test, our tablet browsing test and our smartphone browsing test - in every case the Kindle died in around 6 hours:

General Usage - Web Browsing, Email & Music Playback

Video Playback - H.264 720p Base Profile (No B-Frames)

Obviously these only matter if you're going to be using the Fire as a tablet. As a Kindle, you can expect longer battery life as there's simply less work going on and the majority of the SoC is just power gated during that time.

Either way you're still limited by the fact that the small chassis of the Fire can only accommodate a 16Whr battery. That's around three times the capacity of a high end smartphone battery, but it has to cope with a much larger (and more power hungry) display.

    Who buys both an iPad AND an Android tablet, particularly given your irrational dislike for tablets?

    Very ignorant comments you make.

    Kindle Fire IS trying to accomplish some of the same tasks that the iPad does. Eg web browsing - the key part of functionality in the iPad.

    The probem is, it does it worse, because it is too small.

    iPad and droid tablets are not trying to accomplish what 'laptops do well', at all. They are alternative, lightweight and more simple alternatives when it comes to accessing the web and apps, predominantly. And they do that exceptionally well. There are millions of people who bought them with realistic expectations and therefore kept them, only people with illogical hopes such as the tablet being a work-computer replacement would come away disappointed, and I would be curious which part they didn't realise would happen before they bought?

    If anything is a 'tweener' - it's this Kindle Fire. It does the web / app thing - badly. It does the book thing - badly. It's an attempt to combine the best of both worlds, jack of all trades, master of none kind of story.

    Which explains why it's cheap.

    As for knocking Apple for bringing out devices in 6-12 months (when they have an annual so clearly not a 6 month life-cycle) - how ironic? Lets look at the Kindle release path:

    Kindle 2 - Feb 10th, 2009
    Kindle DX - July 1st, 2010
    Kindle 3rd Gen - July 28th, 2010
    Kindle 4th Gen - Sep 28th, 2011

    Just over 2 years, 4 products. Ironic much?

    It isn't just Apple fanboys who appreciate the use of tablets - it's just people who aren't so ridiculously stupid that they expect a tablet to be a PC. They know what it is, realise its place, and benefit from it enormously.

    Well, I am more of e-ink friend because I wan to read books form my tablet. But the option to read allso net pages would be nice, so I am really much vaiting for coulour e-inks displays!
    They are stin under development, but offer superior display quality over LCD dispays. The problem is speed, so no fast games to colour e-ink, but the consume very little power and offer cood readability to the text!

    About 12 months ago I held a prototype color eInk touchscreen display after a talk by an eInk Corporation employee. It was quite impressive, but the color isn't quite up to glossy magazine / photograph quality, and, like you said, it ran at about 12 frames per second.

    e-Ink consumes power only when switching pages, so when it starts to run at higher frame rates it becomes much less efficient. e-Ink is great when you switch pages every few seconds when reading a page of text, but if you were asking it to play 10 fps animation or support quick-refresh page scrolling, I don't think it would offer much benefit over LCD.

    I own both an iPad 1 and a Kindle Fire. Both are good products, but different. I'm amazed how much my Fire can do at $300 less than an iPad. Having said that I HATE the Amazon Carousel, and quickly learned how to get rid of it w/o rooting the device!

    No problem on the install, but Kindle Books wont launch from Go Launcher.

    Keep in mind the iPad is a previous generation of hardware, and I think it's a little misleading to compare the price points and capabilities of products from different generations. Newer generations of technology always do more for less money.

    Hand the Fire to anyone who has never played with one. First thing they invariably do is bump the power button with their hand. Rest the device against your chest (like when you are reading lying down), 1st thing that happens is power button gets bumped. Look at it wrong and I swear the power button gets bumped by ocular telekinesis magic. Yes you could flip the thing upside down, but having to perform tablet acrobatic to compensate for a crappy layout is stupid.

    It seems not one single person bothered to QA the button design when all that was needed was to move it, or cheaper still, make it recessed or much stiffer.

    This review has almost everything I could ask for. But it's missing one of the most important questions I have: what about privacy?

    How effectively can I use the Fire as an e-reader without providing any personal information - for example, can I just provide a username, password, and something like a one-time-use credit card?

    Smartphones, tablets, and e-readers aren't exactly friendly in this regard. I'd love for reviews of these devices to include a page dedicated to the matter of privacy.

    You can choose to not have your CC/account info saved on the device making one-time purchases possible.

    That's good, but this is an Android-based device. Is it necessary to have a Google account to use it (which would mean providing your real name and birthdate, if nothing else)?
