首先是FCC测试外观照片：
iPad背后标识，WiFi版本实际型号为A1219，WiFi+3G 版本则为A1337。
各种测试场景：
下面就是拆解，固定在背盖上的零件中，最惹眼的就是这块巨大的电池。它包括两块锂聚合物电芯，电压3.75V，总容量24.8Wh。要知道，iPhone 3GS的电池容量不过4.51Wh，MacBook Air电池也只不过是40Wh。
横跨电池的标准iPod接口连线。
拆除之后，可见两根WiFi天线
电池全貌，标号：APN: 616-0447，VPN: DAK 120670-01HH00LH
由于iPad背部为整块铝材打造，屏蔽了大部分无线信号，因此WiFi天线必须艰难的寻找开口。图中接近底部边缘的位置就是一处天线，另一处则位于苹果Logo背后（iMac也是如此设计）。
屏幕一侧
屏幕模块型号依稀可辨为LP097X12，显示其为来自LG Display的LED背光IPS液晶面板。
重头戏iPad主板
拆去屏蔽罩后，可见苹果Apple A4处理器，两颗东芝闪存芯片，以及一颗未知用途的Broadcom BCM5973芯片。另外，这里在苹果产品中罕见的使用了大量环氧树脂固定芯片，足见苹果对iPad可靠性的重视。
主板背面，可见PCB制造商标识AT&S。我们之前很少在苹果产品的PCB上看到此类明显标识。
拆去屏蔽罩后，图中红框位置为电池触点。很幸运苹果并未将电池与主板焊死，这意味着第三方提供更换电池服务的难度又降了一层。
上面提到的那条iPod接口信号线，图中红框处实际上就是面板一侧Home按键的触点。
一点空间也不能浪费，这条线背面还隐藏了WiFi和蓝牙模块。
这里没有出现任何与GPS有关的零件。
屏蔽罩下的WiFi和蓝牙模块，具体芯片无从识别，但有可能是和三代iPod touch同样的Broadcom BCM4329（iPad支持802.11n，而实际上第三代iPod touch的硬件也有此能力）。
红框标出为这条连线的固定位置。
内置扬声器
根据目前的媒体评测，该喇叭的音量足够，音质尚可，不过由于双声道距离太近，很难有立体声效果。
接下来是WiFi+3G版本，虽然该机要到本月底才会上市。但FCC已经将其报告一同公开。这里就是3G模块的位置：电池上方，主板一侧。
3G模块
背面
开启屏蔽罩，可见英飞凌PMB 8878 X-Gold基带芯片，Skyworks SKY77340功放模块，三颗Triquint功放芯片（TQM616035A、TQM666032B、TQM676031A），一颗英飞凌 U6952，以及一颗Numonyx 36MY1EE。左上角的芯片来自Broadcom，不过目前难以辨认。
背面
WiFi+3G版iPad外壳的顶端有一条黑色带，即3G天线，用以传输手机网络信号。红色框中估计为3G模块和主板的固定装置。
除了3G网络，WiFi+3G版还会增加A-GPS定位功能。图中上端屏幕背后金色部分即为GPS天线。而屏幕排线非常类似于苹果Macbook Pro笔记本。

Apple作恶
Amazon Loses E-Book Pricing War
By Brennon Slattery
The world's largest online retailer has conceded to the demands of three major publishing houses and will not discount new best-selling e-books.
Publishers have emerged victorious in the e-book pricing war with Amazon. The world's largest online retailer has conceded to the demands of three major publishing houses and will cease heavily discounting new best-selling e-books, according to the .
Amazon and Macmillan already exchanged fisticuffs about money in February with Macmillan leaving the ring unscathed. Now Simon & Schuster and HarperCollins have joined the bandwagon in refusing to allow retailers to set e-book prices.
In order to stay competitive with Apple's iPad, Amazon needs to keep as many publishers in its corner as possible. After many of them balked at a $9.99 price-point and embraced the iPad's intent to sell e-books in the $15 range, Amazon was forced to reconsider its stance. This news means that rumors of Apple matching Amazon's prices are false given that publishers are now in control.
Interestingly enough, Random House, the world's largest book publisher, still hasn't chosen a side, likely out of fear of the iPad's negative influence on e-book pricing.
My PCWorld colleague Jeff Bertolucci opined that publishers have tunnel vision when it comes to prices and may have a negative impact on the growth of the e-book market.
Amazon declined to comment on the Wall Street Journal article.

It would be interesting to know what the cost to the publishers is that justifies this increase. I mean with actual paper books I can understand, as they have to actually manufacture the book, ship it, pay the overhead on stores, employees, etc. With an e-book it would seem to me that the majority of that overhead is gone? Although I do suppose that $15 is still about half price of what it would cost in the stores. Still if you order a book online through Amazon, or through Chapters/Indigo you can get best selling hard covers for anywhere from $15-$20. Hard to see the justification of the price increase on something that should have very little overhead, except a desire to make more and more money for the publishing company. Of course that shouldn't surprise me. Of course I could be wrong.

You can buy some brand new just released books for $9.99. Why should I pay that for an eBook copy, that once it is made the first time needs no more manufacturing or shipping whatsoever?
