It’s been a bumpy ride on the Blu-ray road, but Sony’s finally managed to get their dual layer writable Blu-ray discs to market. Each disc is around $48, which at a dollars-to-gigabyte ratio, loses to DVD recordables right now. That should change within a few years, but the meantime, DVD is still the champion for thrifty burners.

Those thinking of using these Blu-ray discs for backup purposes should probably wait until the prices drop, or at least until the 50GB dual layer rewritable discs are available later this year.
