Not sure I follow you. Most desktops are some flavor of Windows, call it +90%. What piece of technology, not present previously, became ubiquitous on Windows once it was open sourced? Open sourcing java doesn't mean much for end users on the desktop, imo.

The commercial open sourcing of java will matter on the ecosystem and it's a good thing for java developers (which, despite HN demographics, there are still millions of). Particularly, when you consider the flaws of the JCP and Sun's control to this point.

Good going Sun indeed--stick to making awesome hardware.
