There is one use case for Blu-Ray that Apple does not have an answer for yet. Home movies that people have taken with their HD camcorders, that they want to keep on permanent medium, play easily on their home theater, and not necessarily upload to youtube or facebook.
Until Apple offers free online storage for high bitrate movies (keeping them on a huge hard drive is ok, but even a terabyte drive wont hold more than a year or so of a typical families precious memories, and you would want some form of cloud backup anyway rather than relying on a hard drive not crashing), and we all have 25Mbps+ bandwidth to support it, AND I can watch my home movies without buying a special device like an Apple TV or whatever, then they are still not competing with Blu-Ray for home movies, or hobbyist film makers.
You know apple used to focus on the creators rather than the consumers, but their attitude towards blu-ray assumes we are only interested in consuming content.
I have a handful of blu-ray films that I bought when i got my PS3, watched once I never watched again. But I have stacks of home movies burnt on blu-ray that we watch all the time.
Blu-Ray isn't a permanent medium. Don't expect to be able to read all the discs after 10-20 years.
Look at how quickly recordable CDs and DVDs detoriates. The manufactures promised a lot longer life time when they launched them, but reality was different.
There isn't any media which is permanent. The one that comes closest is non-acid paper stored in a vault.
I hope you have backups of those blu-ray discs: even assuming the media doesn't get lost, disappear in a fire, flood, etc. it has a limited lifespan before the media deteriorates.
The manufacturers quote lifetimes which are far in excess of what's actually been verified - and that's for professionally produced media, not the home burners which generally use less durable media. Our guidelines recommend a 5 year lifecycle for archived media: http://digitalpreservation.gov/you/ That's conservative but at times I'm inclined to give up on tape, disc, etc. and simply say that you shouldn't rely on anything which isn't online and regularly verified (e.g. ZFS scrubs or manual checksum validation) - and since Blu-Ray hasn't sold particularly well combined with general consumer electronics trends makes me hesitant to say that you should assume easy access to a compatible drive over a decade from now.
