Microsoft is still partying like its 1995 up in New York City and for good reason – Windows 8 is launching at midnight. All the major software developers are joining in the fun by letting everybody know that their respective apps will be available on the Windows Store at launch. So far, Google, Hulu Plus, Skype, StumbleUpon, and Netflix have detailed their apps. Now it’s Amazon’s turn.

Amazon announced today that the Kindle app is now available to all PCs running Windows 8. The app is everything consumers love about Kindle wrapped up in a Windows 8 touch-friendly package. The app features over 1.5 million books and over 200,000 exclusive titles that you can’t get anywhere else.

“The Kindle ecosystem offers customers massive selection and the lowest prices, along with hundreds of thousands of books that are only available in the Kindle Store. We’re excited to make the best content selection, along with all of the benefits of the Kindle ecosystem, available on Windows 8,” said Dorothy Nicholls, Vice President, Amazon Kindle. “We’re thrilled that leading manufacturers have selected the Kindle ecosystem for pre-load on their new Windows 8 devices.”

The app is free to download and works on all Windows 8 and Windows RT devices. It also features the same “Buy Once, Read Everywhere” promise that lets you purchase books on one device and access them from another via the same Amazon account.

“We’re excited that Amazon created a Kindle app designed especially for Windows 8,” said John Richards, senior director of Windows App Marketing for Microsoft Corp. “Kindle’s great content ecosystem and immersive experience on Windows 8 make it a great choice for our customers around the world.”

The Kindle app will come pre-loaded on some Windows 8 devices at launch. For everybody else, it’s available on the Windows Store.
