So, if I want to watch the Olympics online, I need to install Microsoft Silverlight. And if I’m interested in good-looking new high-end compact cameras, I’m super-interested in the new Nikon P6000; which writes a RAW format that can only be read by Microsoft WIC, available only on Windows.
Open, non-proprietary equivalents to all of these, which do not constrain your customers’ choice of platform, are widely available.
Nikon is a competent camera company. The IOC is a competent sports impresario. The Chinese government is a competent authoritarian dictatorship. Pity they’re all so fucking stupid about technology.
