How is it somehow easier to just put your dvd/blu-ray drive and "just works" verus downloading a few hours just to watch a movie, and for streaming, what happens if you are in a places without internet connection?
I think that the SD cards will replace the CDs and DVDs. The new ones can hold alot more info. They are smaller and more portable, won't scratch etc.
In fact I think some movie rental kiosks are already employing this technology. Instead of renting a DVD, you just insert a SD card and load the movie onto it which expires in a set time. But even that is going to be replaced in time by downloaded and streaming movies. People will have movies stored on their computers/tvs in the future and not on bookshelves in endless DVD cases. Plus if you travel and can't stream movies....you can just load your computer with the movies you want to watch before you go. I mean, who wants to carry a bunch of DVDs with them when they travel when they can just store em on their HD?
I remember how I used to bring a notebook full of audio CDs with me when I went on a long trip. Then the iPod came along, and NOBODY carries their entire CD collection with them anymore. Doesn't make sense.
Now the same thing is happening with video. I know it hurts people who spent insane amounts of money on a huge DVD collection...but that's progress for ya. I think it's a good thing. I was getting so sick of the studios forcing people to constantly replace their DVD libraries with DVD, then Blue Ray. What was next? Super Blue Ray? Digital libraries are soooo much easier. Not to mention more environmentally friendly.
More and more software is being downloaded too. And I think really large programs will make the shift from CDs to SD cards as well.
