Irony alert
OK, can anyone suggest a use for 25Gb storage on a disk burned on a home PC? Perhaps someone who has gone loopy with the home movie camera? Or someone who has copy and pasted hundreds of 10Megapixel photos directly into a PowerPoint presentation?
Call me cynical, but won't by far the most common use of the new disk format be the storage and distribution of pirated music and video content? How many DivX movies can you fit one one of these babies? How many people have legal mp3 collections that need 25Gb storage?
Its just lucky that Sony isn't the kind of company to limit a technology just because it's commonly used by copyright infringers (or did the Sony Walkman only play store-bought music casette tapes? I forget...).
Sony... the pirate's pal.
