This article is very misleading. On the consumer front end and in many businesses they just want things to work. There is nothing wrong with that, but open source does not always offer that. What it does offer is the ability to take the framework of something and tailor it to how you or your organization works and not conform to the the way a vendor decided software should work. The open source movement has also made strides to integrate with the homogeneous networks of Mac or Win machines. Some of the most widely used and even defacto standard software for some things is Opensource or derived from it. As a perfect example of that let us not forget that MacOS is just BSD Unix with some killer software running on it. Darwin the MacOS underpinning is even free. And let us not forget the idea of an app store really had it's seeds in the *nix world where repositories of software have been the way to get software for years, Apple and Microsoft are just catching up to that model.
