GPU Performance
I threw GLBenchmark on the Kindle Fire (Android apps can be sideloaded via USB and a file manager to run the .apk) to see if Amazon skimped on its GPU driver optimizations. Luckily it didn't, the Kindle Fire's PowerVR SGX 540 performs just as well as you'd expect it to:
WiFi Performance
Amazon didn't sacrifice compute in building the Kindle Fire, but WiFi performance is pretty bad. As I alluded to in our earlier piece on Silk performance, the Fire is limited to around 15Mbps over 2.4GHz 72Mbps 802.11n (5GHz isn't supported):
It's unclear if this limitation is due to the TI WL1271 chip on-board or if Amazon just didn't tune the WiFi driver stack for performance vs. power consumption. I'd assume the latter given the focus of the Kindle Fire.
I also measured transfer rates over USB 2.0 to confirm this wasn't some NAND performance limitation. The Kindle Fire uses a single 8GB eMMC package from Samsung. Sequential read speeds were nice and high at 24MB/s, but sequential writes to the device were noticeably lower. I measured between 4 - 6MB/s, which isn't unheard of for low-end NAND. The lowest sequential write speed I measured is still 2x the speed of the fastest transfer I recorded over WiFi, so this is definitely the result of the wireless stack.

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!http://www.northstarnerd.org/econtent/2011/11/pers...

No problem on the install, but Kindle Books wont launch from Go Launcher.PeteH - Thursday, December 8, 2011 - link
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.adamantinepiggy - Tuesday, November 29, 2011 - link
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.Stuffster - Tuesday, November 29, 2011 - link
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)?
