I've never owned an LD player, but know a few folks who have since adopted Blu-Ray and other formats, but have 1000's of discs, several worth a ton of dough. Some titles have cuts and versions never released on any other formats, so it's pretty cool, especially for collectors. All part of the last remnants of the physical media format
Just got the Return of the Jedi laserdisc for Christmas, along with the Criterion laserdiscs for Citizen Kane (Criterion laserdisc spine number 1!) and Beauty & the Beast. Pushed me above fifty LDs in my collection. Beautiful but space-consuming!!
