The tech blog All Things D on Wednesday released a trove of videos of Steve Jobs at Apple conferences from 2003 to 2007, free on iTunes. In the seven onstage interviews, Jobs explained how his-and Apple's-philosophy is evolving, and he stressed the importance of building products for their actual uses, not "orifices" like corporate IT departments or cellphone carriers.

He explained why it was often more important to decide what products and features not to build than to pick the ones that were built.

He also discussed his competitors and even appears in one interview with Microsoft founder Bill Gates.

Here is a link to the iTunes store where the videos can be downloaded free of charge.
