A dual-layer Blu-ray disc can store an impressive 50 gigabytes, but discs which can hold 20 times as much data have just taken a step closer, thanks to new materials that make reading and writing 3D holograms more reliable
That's great, but I think there are limits to how much storage a person realistically needs. More storage means a better picture, but then you have to make better televisions to see that picture. And there are real limits as to how much better a picture can get and be noticeably better.
For many people this type of instant universal access is better than owning. No responsibility of care, backing up, sorting, cataloging, cleaning, or storage.
I think this would be awesome. Some people would balk at it because they like to have collections of things (which I can totally understand), but I'd really dig it. I think this is a pie in the sky idea, though. There's a lot that would have to be worked out logistically, and I'm not sure if it's even feasible. But it's a cool idea.
I have another update, though. I got a wireless connection for the PS3 primarily to play games online, but I also noticed that I can rent movies on the PS Network. I rented Solaris (standard def) and it was pretty cool. The movie took a while to download (maybe 15 minutes) and you can only play the movie for 24 hours after you started the download, but it was very convenient. The problem with the PSN is the lack of selection and the insanely high prices. But a Netflix player solves both problems, so I might pick up one of those this year.
