In the video, is the last application that opens when Longhorn starts up a package manager ? I've never really understood why both Microsoft and, especially, Apple have never tried to adopt a model similar to the one used by Linux distributions, positioning themselves as the intermediary between the end users and application developers. I suppose this is because they were focused on enterprise customers, and there was already a model in place for shipping software to such customers. However, for home users, installing applications have always been a tedious process that is full of risk.
