Amazon.com has announced "Kindle for Mac," a free application that lets readers around the world enjoy Kindle books on their Macs.

The U.S. Kindle Store currently offers over 450,000 books, including New Releases and 102 of 111 New York Times Bestsellers. Kindle books can now be read on the Kindle, Kindle DX, iPhone, iPod touch, BlackBerry, PC and Mac, and, soon, the iPad. Customers in over 100 countries can go to http://www.amazon.com/kindleformac to download the Kindle for Mac application for free today.

Kindle for Mac features Amazon’s Whispersync technology that automatically saves and synchronizes bookmarks and last page read across devices. A customer can read some on their Mac, read some on their Kindle, and always pick up where they left off.

According to Jay Marine, director, Amazon Kindle, with Kindle for Mac, readers can:

° Purchase, download, and read hundreds of thousands of books available in the Kindle Store.

° Access their library of previously purchased Kindle books stored on Amazon’s servers for free.

° Choose from 10 different font sizes and adjust words per line.

° Add and automatically synchronize bookmarks and last page read.

° View notes and highlights marked on Kindle, Kindle DX, and Kindle for iPhone.

° Read books in full color including children’s books, cookbooks, travel books and textbooks.

Several features will be added to the Kindle for Mac app in the near future, including full text search and the ability to create and edit notes and highlights, Marine adds.
