【精】Paperwhite 2代新版跟旧版1代比较有哪些不同?
亚马逊于2013年09月04日发布了第六代Kindle阅读器，即新版的Paperwhite，官方命名为：All-New Kindle Paperwhite，新款的Paperwhite于9月30日正式在Amazon.com上线，但目前在亚洲还没现货，日本至今还是预约状态（所说10 月30号上市），中国上市还没有时间表。那我们结合新Kindle Kaperwhite的主要功能，看看All-New Kindle Paperwhite跟kindle paperwhite相比，有哪些改进的东西值得我们期待。
-
先说一下第一代kindle paperwhite 用户使用中的不足之处
- 性能方面：从普通用户的角度来说，最大的弊病莫过于触摸屏反应和翻页的迟缓。
- 系统功能：比如：查看单词时，还要进入到一个新的页面，然后从这个新页面回退到书籍页面的反应也比较迟缓。
- 内置阅读灯不是很给力，光源有点不平均，有阴影问题。
-
在新一代的Paperwhite中，亚马逊已经从三方面着手解决了以上遇到的问题。
- 更快的处理器，比上一代快25%；升级版的触控技术，传感器密度提升19%，更精确地响应手指的滑动。
- 全新的翻页操作：在不离开当前页的情况下预览其他页面、章节，查字典，查看wiki，全书X-Ray功能，迅速继续原来的阅读。
- 升级至第二代内置阅读灯。第二代阅读灯有明显的质量提升：在旧版paperwhite中，有用户抱怨在屏幕底部的一排LED灯会产生轻微的阴影，但在新版中完全看不到这种情况，而且亮度更加明亮并且均匀，看着更加舒服
下面结合新kindle paperwhite的主要功能特性(英文摘自官网)，我们一项一项来比较
1、 Whiter Screen, Darker Text
IMPROVED—Enjoy even better contrast on the latest Kindle Paperwhite. Whites are whiter and blacks are blacker, creating sharp, clear text. The high-resolution display allows for elegant typeface options including Baskerville and Palatino, and all fonts on Kindle Paperwhite have been hand-tuned at the pixel level for maximum readability and comfort.
白纸黑字
对屏幕的改进：屏幕像素数增加62%；对比度增加25%。这样让白的更白，黑的更加黑：让字体更加清晰明了。手动对对字体进行了像素级别的调整，让阅读更加舒服
2、Fast, Easy Page Turns
IMPROVED—The new Kindle Paperwhite's processor is 25% faster. Books open and pages turn faster for a seamless experience. Kindle Paperwhite also uses the latest in capacitive touch technology, more accurately responding to the smallest touches.
更快，更简便的翻页
改进：新版的CPU处理器到了1G，处理器提升了 25%，屏幕传感器提升19%。阅读时翻页可以感觉明显更加快了，而且对触屏更敏感。

18、Kindle MatchBook
COMING SOON—For thousands of qualifying books, your past, present, and future print-edition purchases will soon allow you to buy the Kindle edition for $2.99, $1.99, $0.99, or free.
购买实体书后，电子书有超高折扣
如果你购买了实体书，那kindle版本的电子书只需要最低$0.99（9毛9啊，我没看到过天朝有这么便宜的书）。
最后总结
结论：“硬件升级”这个是所有电子产品更新换代的必然结果，但功能上最受欢迎的应该是那个查资料不用新开一页和单词卡片功能了吧。给经常查资料和学英语的同学带来大大的方便。
悲催点：All-New Paperwhite 在日本目前预定价格：9980日元，折合人民币600多，相信大家都在等待日版上市吧！！！
但 日版All-New Paperwhite在官网上明确说明不支持中文，至于是不支持中文菜单还是压根没有中文字库（看不了中文书）没有明确说明，因为目前日版还没出货，所以 也无法验证。但如果真的是不幸言中，不能看中文书的话，那只能寄希望给”多看“系统了。。。看来亚马逊真的是怕了中国强大的海淘，直购，深深伤害了亚马逊 中国的销量！！！
基于电子产品买新不买旧的习惯（除非你不喜欢触屏，那目前可以选择 物理键盘的Kindle5）,如果目前你想入手一部Kindle的话，那新版肯定是你不二选择，因为按目前官网价格，All-New Paperwhite价格跟旧版是一样的：广告版：$119，非广告版：$139，只是国内还没上市。
当然如果你已经有一台paperwhite了，那除非你是超级kindle控或者集邮控，新版也绝对不会让你失望。否则的话毕竟新版只是改进版，无论是软件还是硬件上并没有质的飞跃，如果没有迫切需要那还是期待下一代产品吧！
