I've questioned whether it's worth upgrading to BluRay. I decided no. The BluRay players and discs cost a lot, and I'm already fine with DVD quality. I wouldn't really see a difference anyway.

I'd wish HD-DVD would have won. It was much more cheaper, offered just about as much high-def as BluRay, had interesting interactive qualities, and could always have been layered for more storage. I guess people just wanted the format war to end quickly without thinking.
