I see your point, but how often do you use them?
I’ve got a NAS spinning, backed up to an external drive, also backed up to Idrive offsite.
But if I buy a film it’s now from iTunes, music I use AM, watching is Netflix.
Other than backing up my Mac I’m not sure why I keeping all this in place other than as a keep sake, I guess the modern age is turning the majority away from being file savers.
I remember the old days on here and the majority of the discussion seemed to be about ripping, file storage and backups, that discussion has gone.
You can't be much of a movie fan if your only real source of movies is Netflix. It's also very poor quality compared to even iTunes.
How often do I use them? A LOT. There's a few reasons:
1> My ISP still has bandwidth limits (currently at 1TB a month). Playing the title locally off my hard drive neither uses any bandwidth from the Internet nor slows down any other connections in my house using it.
2> Blu-Rays at the same resolution have higher quality video than the iTunes versions (I just directly compared Raiders of the Lost Ark and there is no contest). If you're watching this on anything but your phone, it's visually apparent. The 4K iTunes versions are typically better than 1080p Blu-Ray, but then UHD Blu-Rays at 4K are better than iTunes. Services like Netflix are typically much lower quality than iTunes and even less quality than Blu-Rays.
3> Blu-Rays have higher quality sound (usually DTS-HD Master Audio or Dolby True-HD based, with or without Atmos. DTS:X is not available on iTunes. iTunes is either Dolby Digital Plus based for 7.1/Atmos titles or old fashioned Dolby Digital for 5.1 titles, both of which are lossy based formats whereas DTS Master and Dolby True-HD are lossless).
4> You typically get the digital copy with most newer Blu-Rays (sometimes you get the 4K version from Apple with the 2K disc code; I've got dozens like that). Often, I've found the Blu-Ray (with a digital copy mind you) for older movies costs $4-8 while the iTunes version might still be $10-15. It makes ZERO financial sense to buy the iTunes version at $10-15 if you can get the Blu-Ray with digital copy for less.
5> It's much harder to remove DRM from iTunes copies than Blu-Rays and impossible for 4K iTunes files as only an ATV 4K can even access them. I can dump 4K UHD BDs all day long and they will play with any digital media player that can play MKV like KODI. You don't have to worry about iTunes servers disappearing 20 years from now and ending up with NOTHING (if that sounds crazy, Ultra-Violet is GONE this summer already. You don't know what the market will bring).
6> iTunes versions of Blu-Rays that have DTS:X are only in 5.1 on iTunes (with the exception of Jurassic Park Fallen Kingdom which has an Atmos version on iTunes and DTS:X on Blu-Ray and UHD Blu-Ray)
7> Other than Vudu (which uses inferior SBS), 3D movies are only on Blu-Rays and I'm a big 3D movie fan (92" screen with 3D projector).
I mean you can argue convenience all you want, but trading flawless CDs for lossy digital "Rent-A-Center" music you don't own and which they can take away as contracts change doesn't interest me very much. You also need an Internet connection (if you think cell service is everywhere you haven't gone hiking much or out in the country or mountains where service is spotty at best or non-existent at worse. Hell, going through a tunnel while driving kills everything but the CD/local drive players. If you own the music, it's not hard to keep a cheap USB stick around (I have a virtual radio station on random that plays only songs I like and requires no cell service or contract as I already own 12,000+ songs so why on Earth would I want to rent them from Apple Music?)
Or trading a home theater experience for a 6-8" phone or slightly larger tablet...well sorry, but I like the movie theater experience not the 1980s portable television experience. Retro is one thing, but a phone is not a cinema and neither is a 55-65" TV. I'm at 92" and looking to go to 115" soon (as large as will fit on my wall in my home theater).
