I wouldn't chuck out that new Blu-Ray player just yet. An innovation like this usually takes awhile before it comes to market (and even longer before they're ubiquitous enough for most folks to consider adopting it). But it's easy to see how something like this would eventually supplant everything we've come to know about optical storage and playback.
Between this and the stuff happening in the realm of flash memory, this is very very cool. I'll certainly be watching for more about it.
