如何寻找超级成长股？世界首富24封股东信“吐露天机”：现金流比利润更重要(26)

十一、2007年：Kindle的诞生
我需要强调Kindle开发了实体书籍不可能有的实用功能，如果你遇到不认识的字，你可以轻松查找。你也可以搜寻你的书目。你的笔记和划线都会被存储到云端，永不丢失。Kindle也可以自动翻到你上次阅读的地方。如果你的眼睛累了，你可以调节字的打消。更重要的是，它可以无缝地，轻松地找到你要的书，并在60秒钟下载下来。
I‘ll highlight a few of the useful features we built into Kindle that go beyond what you could ever do with aphysical book。 If you come across a word you don’t recognize， you can look it up easily。 You can search your books。 Your margin notes and underlinings are stored on the server-side in the “cloud，” where they can‘t be lost.Kindle keeps your place in each of the books you’re reading， automatically。
