Besides gaming what else can be done with a standard ps3?

Things I have considered include putting my tv's pc somewhere else and running plex off the ps3 for my movies and series.
Has anyone done this and is it worth the cash for a switch?

Something else I read plenty about and tried a few times was remote play on an android (Specifically an unrooted s4) but I got nowhere with this, all links for the apk's I found were either dead or linked to viruses.

Is there anything you guys did/do with yours besides play games?
