The thing to celebrate is the landmark deal between Microsoft and Novell to improve interoperability between Windows and Linux. What's really cool about this agreement is that it acknowledges the fact that so many of you manage mixed-source environments and that, to support you effectively, we have to bridge the divide between open source and proprietary software. To that end, Microsoft and Novell will create a joint research facility to pursue new software solutions for virtualization, management, and document format compatibility. This isn't so much about Microsoft embracing Linux; it's about supporting the choices that customers make and making it easier to deploy Windows in Linux environments and vice versa.
