Fact of the matter is all the cool kids have consoles.
ok all seriousness from this point on; I just don't understand the need to downplay or convince other gamers that their choice of platform is a bad investment.
To answer the OP: I like having physical copies, my the collector's editions, and just having it sit there on the shelf is a thing of beauty. Getting it signed by the makers is even better. I even remember back in my junior, and high school days my friends and I was sharing playstation and dreamcast games. Being a kid back then and playing games that you borrowed from a friend was freakin huge because it means you didn't have to buy it to play it. (And before you can say "You can share on Steam too!" Well it's not as simple as just handing over your game, other people can only play your games when you aren't using them and, I think you have to log into Steam on that friend or family member's PC to authorize it) And why the hell do I have to explain that here? I shouldn't have to.
TLDR: It's not a negative owning a playstation console, it's more of a net gain. I can always expect Sony's first party studio to deliver high quality games that appeals to me, and that is what it really boils down to. My PC is for anything else that pushes my GPU, and MMOs.
