You know that Microsoft see's you as a threat to their business when they begin to copy you. Publically, they'll deny that you even exist. Ask a die hard Mac user.
So, it should come as no surprise that Microsoft has released an installer much like the Ubuntu installer (Source: http://www.microsoft.com/web/channel...Installer.aspx) that will distribute an open-source product called Drupal (source: http://news.cnet.com/8301-13505_3-10...orsPicksArea.0). Beyond that it's finally offering support for Linux users with Silverlight 2.0.
Could it be that they're finally beginning to lose customers to Linux? (See Amazon top 20 laptops)
I believe that it was Steven Ballmore who said that "Linux owes Microsoft". Hmm, well, You're welcome Steven.
