kindle 499和899的有什么区别

在新一代的Paperwhite中，亚马逊已经从三方面着手解决我遇到的问题。分别是：
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。
全新升级的内置阅读灯，解决不平均，有阴影问题。

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.
