Blu is not dead yet..
Bluray is dead? Really? I sure as HELL am not going to go spend $18,000 on one of these machines... BD already has prototype discs that can hold 200GB+, and they sure don't cost $180 per disc. If you are looking to archive that much data to begin with, you're going to want several copies.
I'd rather have six 50GB discs (300GB) for ~$210 total (allowing me to have redundant backups), than 1 disc that ACTUALLY lasts god knows how long for $180 'in volume' (how many?)
$30 extra for redundancy is well worth it in my book.
What happens if one of those 300GB discs burns incorrectly? What a waste of almost $200....
All that being said, I'm all for holo-storage, but it just doesn't seem reasonable yet..
