Review Summary:

After I purchased my Kindle Fire HDX, I noticed a pretty bright blue/purple streak that never went away on the sides of the pages. Going into Sepia and changing the background pages did not help this issue. I called Amazon and they replaced it with a new one. The new one has the same blue/purple border on white and light background pages. The Amazon replacement is more subtle and even around the edges, so I opted to return the one that had the darker border.

On Amazon's description of the Kindle Fire HDX that they actually mention this defect as being normal and I quote below:

''You may notice a very narrow, faint blue tint around the edge of the device when looking at items with a white background, such as books or web pages. All displays have some level of light emission around the edges, and the light on the Kindle Fire HDX 7'' inch is blue due to the technology used to render perfect color accuracy. Most LCD displays use white LEDs, and then apply filters to extract the desired color. The result is oftentimes a compromise to tone and color accuracy, or--if attempting to address these compromises--an increase in battery consumption and, thus, device weight. We've taken a different approach. To achieve the perfect color accuracy on Kindle Fire HDX 7'' inch at the lowest possible battery consumption and device weight, we used blue, not white, LEDs. Blue LEDs allow for a much more accurate and rich representation of color and result in an up to 20% improvement in power efficiency.''

For avid readers, this is a serious flaw that is irritation and presents a problem. I prefer to read on other tablets or devices that do not give me this same issue. It even happens with the browser sometimes as well. I understand the reasoning for LED light use and why blue is better than white and the benefits of lower battery consumption. However, I am very critical of this decision as I do not believe it helps this tablet overall. Web browsing speed and the speed for everything else is wonderful! This is leaps and bounds faster than last year Kindle HD. Last year Kindle struggles to go through any HD video content I put in.

This year's HDX able to play seamlessly all the HD 1080p contents I added. It is incredible how much the 2.2Ghz quad processor improved vs last year's model Dual 1.2Ghz. The screen is in true HD 1080p (1920x1080). This means any HD content I throw at it will view in its intended resolution. The screen is crystal clear (much better than iPad mini) and the viewing angle is incredible. I have this Kindle hanged in the middle of the car and at any seat it is view very clearly. Last year's model was not as clear as this. This is excellent for my minivan with my kids watching all the HD movies. The brightness of the screen is also much brighter than last year's model. The battery life is not as good as last year's model. This is quite logical as last year's HD has a 4400mAh battery while running 720p while this HDX runs Full HD 1080p but runs only on a 4500mAh battery (only 100mAh more than last year). Overall this tablet does very well and it is a good buy.
