Kindle for ...

Kindle has many versions.  Kindle for Mac, PC, Android, and iPhone.  But because Linux needs open sourced, there is not a Kindle for Linux.  Don't worry.  Using Amazon Cloud Reader, we can have Kindle for browsers.  For example Firefox 6+.  PC is much more powerful than a pad.  Also I have PC everywhere.  I found it comfortable to continue my reading everywhere without carrying anything.  The only difference for a browser version is that it doesn't have a Oxford English dictionary.
