????7寸版HDX采用720p前置攝像頭，分辨率為1920×1200像素，但沒有后置攝像頭；而8.9英寸版HDX增加了帶閃光燈的8百萬像素后置攝像頭，分辨率為2560×1600。兩款設(shè)備都配備了16 GB內(nèi)存，并采用一體成型的漆黑色鎂制底座，比去年的機(jī)型輕了34％、薄了14％。亞馬遜稱，由于采用了新的低功率模式，能在任務(wù)較輕時(shí)減少芯片使用，這幾款新機(jī)型的續(xù)航時(shí)間達(dá)到了11小時(shí)。假如用戶只讀電子書的話，續(xù)航時(shí)間更可長(zhǎng)達(dá)17小時(shí)。兼容美國(guó)電話電報(bào)公司（AT＆T）和威瑞森（Verizon）網(wǎng)絡(luò)的4G機(jī)型也將于12月面市。

????當(dāng)我拿起兩種型號(hào)的HDX，第一感覺是輕得不可思議。8.9寸版HDX僅重0.8磅（約合363克），比10寸版的iPad輕盈了許多，后者的重量“足足”有1.44磅（約合653克）。市面上有許多7寸屏以上的平板電腦，我認(rèn)為HDX是第一款我能長(zhǎng)時(shí)間舒服地握在手中的產(chǎn)品。

????重制版的Fire HD同樣引人注目。蘋果（Apple）此前將大量iPhone 5部件塞入“高端大氣”的彩色塑料殼中，誕生出iPhone 5C。亞馬遜這次如法炮制，新款Fire HD的硬件和去年的高配版保持一致，依然是1.5GHz雙核處理器和1280×800分辨率屏幕，不過外形進(jìn)行了重新設(shè)計(jì)，采用了類似HDX的柔性塑料底座。售價(jià)則是業(yè)界良心的139美元。（對(duì)比一下，僅比今年新上市的Kindle Paperwhite電子書貴了20美元。）

????雖然僅僅將上一年的硬件產(chǎn)品進(jìn)行了重新包裝，但極具殺傷力的價(jià)格讓競(jìng)爭(zhēng)對(duì)手望塵莫及。貝佐斯曾說過，如果價(jià)格合適，用戶愿意同時(shí)購(gòu)買平板電腦和電子書，而亞馬遜這次無疑在低端市場(chǎng)掀起了一場(chǎng)價(jià)格大戰(zhàn)。貝佐斯解釋稱：“我們發(fā)現(xiàn)，我們第一次向大量購(gòu)買電子書的平板電腦用戶（不僅限于Kindle Fire平板用戶）展示Kindle Paperwhite電子書設(shè)備的時(shí)候，他們對(duì)該產(chǎn)品可以說是愛不釋手?！?/p>

????這由此導(dǎo)出了貝佐斯的第三個(gè)原則：“取悅用戶”和“深度整合”之間有著千絲萬縷聯(lián)系。所以，他會(huì)不遺余力地推廣亞馬遜的新系統(tǒng)Fire OS 3.0 Mojito——基于谷歌Android 4.2.2果凍豆的定制系統(tǒng)。貝佐斯竭力向大家證明：最新款的Kindle Fire是硬件和軟件的完美結(jié)合。

????The 7-inch HDX has a 720p front-facing camera, but no rear camera, and a pixel resolution of 1,920 by 1,200; the 8.9-incher adds an 8-megapixel rear camera with flash and a pixel resolution of 2,560 by 1,600. Both include 16 gigabytes of built-in storage to start and come sheathed in a jet-black magnesium unibody chassis that's up to 34% lighter and 14% thinner than last year's models. Amazon claims the tablets will run for 11 hours between charges and as long as 17 hours if users only read e-books. That's thanks to a new, low-power mode that cuts down on chip usage during light tasks. 4G models running on AT&T (T) and Verizon (VZ) will also become available by December.

????When I grip both of the HDX models, I'm surprised at how light they are. The 8.9-inch HDX weighs 0.8 lbs, less than the 10-inch iPad, which weighs significantly more at 1.44 lbs. Frankly, it's the first tablet over 7 inches I could imagine comfortably holding for long stints.

????The revamped Fire HD also warrants attention. Just as Apple (AAPL) took many of the iPhone 5's components and wrapped them up in the 5c's "unapologetically plastic," candy-colored body, the Fire HD takes the same 1.5 GHz dual-core processor and 1,280 by 800 resolution display in last year's high-end model, repackages them in a soft-coated, plastic chassis resembling this year's HDX, and sells it for $139. (To compare, this year's Kindle Paperwhite e-reader is being sold for just $20 less.)

????Yes, it's last year's technology all gussied up for another pass but at an even lower price point few competitors dare go. It's a play for the lower end of the price range, where Bezos says people are more inclined to buy both an affordably priced tablet and an e-reader. "What we've found is we take heavy e-book buyers who are also tablet users, not just Kindle Fire tablet users ... and we show them the Kindle Paperwhite for the first time, we can't get it back from their hands," he explains.

????This brings Bezos to his third principle, a venn diagram where "customer delight" and "deep integration" overlap. He is keen to show off the improved software operating system-- dubbed Fire OS 3.0 "Mojito," using Google Android 4.2.2 Jelly bean as the underpinnings -- and how the latest Kindle Fire experience marries hardware and software services.

????亞馬遜隆重推出Mayday，HDX上通過Wi-Fi連接的7×24小時(shí)客戶支持服務(wù)。貝佐斯非常興奮地點(diǎn)開展示機(jī)上的按鈕，片刻之后，一位名叫迪倫的亞馬遜員工出現(xiàn)在小視頻窗口中。他不但能面對(duì)面地為你答疑解惑，還能手把手的指點(diǎn)你，在你的平板上畫上幾個(gè)指示箭頭，甚至還能按照你的要求完成調(diào)節(jié)屏幕亮度等工作。貝佐斯從技術(shù)角度解讀說：“這是最困難、當(dāng)然也是最酷的事情?！彼A(yù)計(jì)Mayday會(huì)迎來開門大吉，因?yàn)榇蠹叶计炔患按叵胂蚺笥鸯乓?/span>。

????Enter Mayday, a new, free 24/7 tech support service available over Wi-Fi for HDX owners. Bezos gets excited as he taps a virtual button on his demo unit, and voila: In seconds, a tech support employee named Dylan pops up in a small video chat window. Not only can employees offer virtual face-to-face advice on how to use a certain tablet feature, they can actually control the tablet, too, drawing arrows to menu options, even doing things like upping or dimming brightness at the users' request. "It's both the hardest to do and coolest you can do," Bezos says from a technological standpoint. He expects Mayday to be particularly popular initially as users show it off to their friends.
