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.

    No, part of the reason Amazon forked Android was to eliminate Google services and analytics. No Google account required, nothing is shared with Google unless you choose to install their apps and services. Amazon also has very strict privacy policies and does not share user information with anyone(even internally from what I understand).

    As a commuter, I am on my iPad2 3 hours a day. I would love to try the Kindle Fire as a less cumbersome replacement (for me, it either fits in the pocket of the sport coat or it doesn't), but without 3G, there is absolutely no productivity for me here at all.

    Its kind of amazing how little importance 3G is given in the press when discussing Android tablets. They commonly get released with no 3G version at all, and when the 3G versions do come out, they have contracts and pricing which simply can't compete with iPad's liberal Verizon and AT&T month-to-month plans.

    Keep in mind that this great 2011 tablet computer has worse connectivity then a Gen 1 Kindle.

    It's interesting that most reviews from Anand pick apart even the smallest problems, but this review seems to gloss over them. Is it really possible that Anand and Vivek didn't have the problems that other reviewers had?

    Problems mentioned in other reviews include, turning off the tablet when watching movies, browsing, or doing any activity because of the poor placement and implementation of the
    Owner button.

    The need to often tap several times to get the screen to respond, or to find that the tablet did, after a lag, detect a tap, but now moves you to something else because you tapped too often.

    The lack not only of a microphone, but a rear and front camera, so no Skype possible.

    Also no gyro. Amazon doesn't allow apps in their store if it uses any of these features.

    Many side loaded apps either don't work, or have problems if they do. And sideloading apps isn't for the average user anyway, so most are stuck with what Amazon approves, which isn't much.

    Many tap points are small (and as mentioned, not always responsive), and so people with vision problems or motor control problems will have difficulty with this.

    Overall, this isn't such a great product. I'm surprised that Anand didn't go more deeply into this. There's no excuse that it's just $200. For that we should get something that lacks features, but it should still work well for what it does.

    I agree. I feel this review isn't up to the usual high standards. The points melgross states are quite salient. Anand mentions that the Kindle Fire is no iPad 2 but this is for many more reasons than size and graphics horsepower alone.

    I have own a older molder kindle (purchased 6 months ago) I was very pleased with it and still am. Well I had to try the fire. I did not like the back light at all. When you work on computers all day you eyes fatigue. With the older kindle seems like you are reading a book and is much easier on the eyes.
    As far as the internet web browsing it was redundant since I have laptop etc... The film quaility of the movies on the fire was excellent but again redundant.
    Also I could view my external mail account but could not open the messages, so it was useless as a business tool. The fire seems to be much heavier, and do not think for a moment that you can use your old protective cover for the fire. You will have to lay out cash for a new one to fit the fire.
    I returned the fire after a couple of days and am awaiting my refund from amazon. I will continue to enjoy my older kindle for the "book" reading experience, after all that is why I wanted a kindle in the first place.

    "Amazon refused to skimp in two areas: compute and the display."
    "this is more general purpose compute..."

    Please: "compute" is a verb, not a noun.

    This is my single biggest gripe with the browser, especially in landscape, most of the screen is wasted on the buttons and status bar. Unless I'm being really dumb and missed the option to get rid?

    Aside from Netflix, nothing I searched for in the app store was there. I don't think I'm asking a lot...

    1. Zinio
    2. Google maps
    3. Yelp
    4. Firefox, opera or some other web browser to get around the browser irks and the few buggy web sites (typically where pop up ads prevent you from seeing the page, or you can't select things on pop up menus)

    It's time to create a device with both displays and a simple smart cover that shifts the device from one mode to another.

    Isn't it possible, is it?

    The NotionInk Adam is a similar idea to what you're talking about.

    A lot of people say they don't understand the comparison between the Fire and an iPad, but I think there's value to such a comparison.

    Yes, I KNOW the iPad is obviously a superior piece of hardware to the Fire and it was designed to meet different needs. I need to know EXACTLY what those different needs are. What does that extra $400 dollars buy me? I would guess at least half the people reading reviews about the Fire want to know how it compares to the iPad, EVEN IF THEY ALREADY UNDERSTAND that the two are targeting different demographics.
