This week Stephen Speicher and his engadget column The Clicker discusses the five reasons why he believes Blu-Ray will win the battle against HD-DVD. Some of the major points made are format security, computer manufacturer support, and overall capacity. Speicher argues that Blu-Ray has features that will make disc copying difficult, a large capacity already approaching the theoretical limits of HD-DVD, and support from major PC makers Dell and HP - all of which give it the edge over its rival.
