No, they're missing the real advantage to holographic storage: better data integrity.
When a CD gets scratched, you lose actual bits. But with a holograph, every little piece of the disk contains the entire image. Try it with a real holograph some time... cover up the bottom half, and you can still see the entire thing. Even break it in two, and you have two identical (albeit dimmer and with a limited perspective) versions of the original. Just so long as they are smart about the way they implement it, and the sensors are a good deal more sensitive than they need to be, this kind of media should be a lot more robust than current CDs and DVDs, and maybe even hard drives.
A while ago there were several teens who died in Madison Square Garden during a concert. This was before decibel limits at concerts, and their breastbones were pulsating so much that their hearts went into cardiac arrest. Needless to say, there are now decibel limits at concerts.
I'm uncertain about this specific resonant frequency, but it's not entirely myth or FUD.
