has announced that its free software "Kindle for PC" is now available to download for Windows computers with a Mac version said to be "coming soon".

The application means Kindle-less readers around the world can pay to download the more than 360,000 Kindle ebooks to read on their PCs or laptops.

For those that do have a Kindle, the PC software offers the ability to read some of a book on a PC, read some on the Kindle, and always pick up right where the reader left off thanks to the Whispersync functionality.

The software is compatible with Windows XP SP2 and above, Windows Vista or Windows 7 - the latter of which gets touch functionality with compatible hardware including pinching fingers to zoom and coming soon - the ability to turn pages with the swipe of a finger.
