Amazon buys Linux license from Microsoft

"As part of the pact, Amazon will pay Microsoft an undisclosed amount of money.

The deal covers both Amazon's Kindle product as well as the company's use of Linux-based servers. Microsoft has maintained that many implementations of Linux infringe on its patents and has signed numerous licensing deals that cover Linux with both companies that sell Linux-based software and those that use the operating system in their hardware."

WTF?!
