Everything in my house at least uses, if not completely powered by, OSS.

From my wife's computer (Ubuntu), to my computer (Ubuntu, but I also have World of Warcraft on it), to my childrens computer (various Linux distro's), to my phone (N900 with Maemo - powered by OSS, even if it does have closed components.), to my wife's phone (Android-based. OSS operating system, closed google apps)... my entire life is driven and powered by OSS.

To say that it has netted "nothing" compared to the closed source alternatives is ignorance at it's finest. When some of the leading software on the market today (Firefox, Apache, PHP, MySql, PostgreSQL) are all OSS then that's quite a bold, and wildly innacurate statement.

I will admit, it seems to be harder for OSS communities to successfully manage to get a working, viable solution together without the backing and support of a major company (which likely uses non-OSS philosophies in other areas of their business) - I would argue that when they do get working their products are superior to the closed-source alternatives. As, not only are they at least mostly feature-equivalent, but they are also free.. which is a heck of a hurdle to get over when you're not rich.
