Ross Robin suggests that Microsoft wants both of the new DVD formats to fail.
Microsoft wants both Blu-ray and HD DVD to lose. You see, before Microsoft and Intel backed HD DVD, Toshiba was just about the only major consumer hardware brand backing HD DVD. Now, since Microsoft and Intel have hopped on to the HD DVD bandwagon and at least dragged HP part of the way there, HD DVD has become a much more viable option.
I wonder if/when Scoble will weigh in.
