I didn't see the benefits of 1080p in 2001
Why would I see the benefits today?
1920x1080p, or its 4:3 aspect ratio cousin, 1920x1440, wasn't anything spectacular in 2001 on a 21 inch CRT monitor, so why are we all buying into the craze of 1080p? Content.
As soon as we start to see content on 4320p available, we will buy it, 3D tv is a flash in the pan idea and really screws us all over in the end, but 7680x4320 will be a content-driven format, and whatever format we see that content on will be trivial..
I personally would love to see a return of 12" (12 inch) Laserdisc systems as a home enthusiasts technology, but this time with the modern technology that we have today of Blu-Ray and Holographic storage.
Not only would this completely obliterate Piracy rings for a short time (Until we invent stream-capturing devices) but it would also provide a stable and future-proof (for at least the next 20 years, or more) ground for the new higher resolution contents, then maybe we can see a convergence of areal-density on 12" Laserdisc catch up and beat the storage requirements of 7680x4320 content, and even beyond this for years to come.
But no one will do it, no one will build it, why? BECAUSE they all just want us to buy again, and again, and again, and again, and fleece us all out of money, again, and again.
I never got into DVD, I never got into Blu-Ray, why? Because I'm happy with Laserdisc, and I have quite possibly the largest content database in the world available to me, stretching back to the start of stamping out Laserdiscs, in 1979.
You know what has won the storage format wars? Laserdisc, because I don't have to sit there and watch anti-piracy advertisments, you guys do, I'm free to sell, trade, copy, or buy my Laserdiscs from anyone I want, and most of the great movies on Laserdisc were manufactured
All honesty, movies were meant to be delivered in their native aspect ratio, but computers reached perfection in detailing information to the user at the 4:3 aspect ratio, and we need to see a divergence in the LCD screen marketplace to cater for both the movie lover and the computer user, THAT would truly drive sales up for new panels.
