Opinion Piece
The Blu-Ray discs themselves are the natural evolution of
optical storage media. Although the software that has been
developed for the Blu-Ray Disc format is somewhat
disappointing compared the HD DVD’s HDi standard.
This, coupled with the low standards for the first version of
the format (i.e.- no onboard storage or internet
connectivity required) has made the format unfriendly to
early-adopters.
The picture and sound quality of Blu-Ray Discs is far superior
to that of DVD and is comparable to that of HD DVD. The
discs themselves and the players are somewhat expensive,
but prices are falling.
We recommend the format to anyone who wants better
picture quality and doesn’t mind spending a lot more for it.
