! Warning: this post hasn't been updated in over three years and so may contain out of date information.It’s true: Microsoft really has given up on world domination and accepted people will continue to use operating systems other than Windows. In a classic case of “can’t beat ’em, so join ’em”, Silverlight supports both Windows and OS X. Now though, Linux users can get in on the act too, with today’s release of Moonlight 1.0. And it comes fully endorsed (and indirectly funded) by Microsoft too.
