Software becoming is increasingly commoditized, Stein said during his keynote presentation, and more of it is available free and it is easy to get.

He cited the OpenOffice office automation package as an example of free software to replace Microsoft Office.

"As the [open source] stack grows and grows and takes over more areas, there's less money available in packaged products," Stein said.

"All of your software [will be] free. It means that over time, you aren't going to be paying for software anymore" but will instead pay for assistance with it, Stein said.

He estimated that in five to 10 years, most software used today will be free.
