Postchronicle: Blu-ray is starting to become mainstream, thanks to lower player prices and increasing numbers of titles on store shelves. And it'll undoubtedly have a few years in the sunshine, just as DVD did.
But Blu-ray is still a disc-based technology, with moving parts that can wear out, and the discs themselves can be affected by fingerprints that can prevent them from playing properly - as I discovered over the Christmas season when one of my discs froze in the middle of a chapter. Fortunately, once it was cleaned the disc returned to its high def glory, but the point was made.
Next generations of high definition playback could eliminate these problems and it wouldn't surprise me if they end up coming from new generations of the same type of smart cards you may be using today, in your notebook PC, cell phone, digital camera, media player or whatever.
Right now, such cards don't have the storage capacity to compete with Blu-ray's 50 gigabytes, but upping the card ante is happening already - and wouldn't you know there's more than one solution on the horizon and they'll undoubtedly compete with each other.
