I got it replace a PS3 that died, the 2nd one and didn't want to waste more money on a PS3 when I mostly use it for Blurays, SACD and Netflix.
New PS3s don't play SACD, not sure about the PS4 but I don't think that does either.
I'm surprised how poor and slow of an interface the S5100 has though, so much slower than a that was over 6 years old. The PS3 interface was crazy fast, the S5100 is just awfully slow, feels like I'm in the 1980s.
It does crash sometimes when playing streamed video from a NAS, the only solution I know how to fix it is to unplug it.
I didn't get a Panasonic as I don't want adverts in the menus.
