Recently, I have bought a kindle fire for ebook reading. But after I import my computer’s PDF ebooks to my kinlde, I found it not very comfortable to read PDF in Kindle, one of my friends said that it is a good choice for us to convert pdf to mobi for kindle? Really? Could you give me some suggestions for kindle reading? Should I have to convert my pdf to mobi for kindle reading? If, so , how can I do then? Yours every answers is welcome. Thanks very much!
