Of course this comes after I jumped on the Black Friday Amazon HP Blur-ray edition! I shouldn't act so surprised.
And, yes, I have the Laserdisc release of "Star Wars", the Laserdisc collection of the "first" three "Star Wars" movies, the DVD collection of the first three "Star Wars", DVD release of "Star Wars: Phantom Menace", but at some point I said, "enough!"
Like my ears, my eyes are now starting to let me down. Ironic that by the time technology has brought HD and UHD to an affordable level, I can't appreciate the extra resolution like I would have enjoyed 30 years ago. Same thing with audio, I spent more money getting lower distortion levels and higher range speakers than I can appreciate now. If I had the money I have now to send back to 30-year old me, I'm sure I could have put it towards a better pair of speakers.
So, at some point, wealth, cost, technology, and biology all converge on the "Sweet Spot" of diminishing returns. Sure, my next TV purchase will be a 4K OLED, but my HD Samsung LED-backlit TV has to die first. And then will begin the process of replacing just about every piece of kit in my Entertainment Center. 4K requires UHD Blue-Ray, which requires 4K UHD-capable AVR, which would benefit from an Atmos set of speakers (or two) and so on and so forth.
It's like any home improvement project, it snowballs out of control!
