The big thing I’ve run into is regular use vs occasional use. I only use my PS4 as a Blu-ray player these days, and each time I turn it on, it has to figure out if it shut down correctly last time(of course not). Then, after a memory check, it boots. I sign in, and then it yells at me that it has a mess of OS updates to install, which I don’t want to wait for because I just want to watch this damn movie. Plus, my controller barely holds a charge anymore, and if I don’t use the right USB controller plugged into the PS4, the controller doesn’t pair and control the damn thing. If I were using the PS4 every day like I did back in 2016, a lot of these problems wouldn’t be there, but because I boot it once every 3 months, it’s a hassle.
I would love to be able to just slide in a disk and watch in the rare cases I’ve decided to. As it is, I’m about to buy a dedicated Blu-ray player instead of using the hardware I already have.
