In a research report from Evans Data Corporation we learn that last year's decline in the targeting of Windows as a primary development platform has been repeated. John Andrews of Evans says "it's clear that a shift away Windows began about two years ago, and the data show that this migration is now accelerating. Linux has benefited, but we also see corresponding growth in niche operating systems for non-traditional client devices. The landscape is changing."
If I were a Microsoft shareholder I might be happier if I could see Microsoft engaging more aggressively with the open source community. It's difficult to steer something with the inertia of a large organization like Microsoft, though, so perhaps they are changing course as fast as is practical. Ultimately even Microsoft will have to realize that they can't do everything by themselves, and specifically that they can't dictate standards (e.g. WSDL) to the rest of the world.
