500KB/page at $0.02/page = $20.97/GB. HDD is $0.01-0.03/GB, SSD is $0.10-0.25/GB, BD/DVD are $0.02-0.10/GB, respectively, at retail prices and before counting redundancy. $20/GB was as far back for HDD as Oct 1999, which by the way fell further to around $7.50 next year in Oct 2000[1]. Yeah interesting but 10-100 fold density improvement would be nice...

25G BD-R can be had for 8 ct. However, the patent license royalties are at about 10 ct (I forgot if USD or EUR). Also, you can't retroactively pay the royalties when importing. Patents are bad. They would have developed BluRay without patent protection.
