I'd say keep it, or at least keep your favourite and most repeatable games out of the lot.
If that's really not an option though, have you considered donating to a local children's hospital? They probably won't take the more mature games, but they're probably the ones that sell for the most money anyway.
I was on the sofa with my girlfriend and she could tell something was wrong. She was very understanding, she knows how much Giant Bomb stuff I watch, even if she thinks it's dumb. She might not have immediately got it, but I think in a small way she knew what this meant to me.
She's been uncharacteristically nice to me since, it's weird...
You only need to listen to a few minutes of Jeff talking inside baseball about running a video game website to know that that guy is a motherfucking genius who knows his shit. If anyone can recover from this, it's these hard ass motherfuckers right here. I can't wait to see what the next chapter of Giant Bomb looks like.
You say it's easy to rationalise why you prefer the Xbox One. The thing is, the consoles are actually so similar it's very easy to spin it one way or the other. It all depends on what you're looking for. There's counter-arguments for all your points:
Online Gaming - I have high speed broadband and XBL drops out for me all the time, preventing me from accessing my arcade games (as I bought them on my previous broken console) and screwing me over in multiplayer. The fact that Sony is now charging for multiplayer gives them the ability to really bolster the service.
Controllers - Microsoft has hardly changed the controller at all, where as Sony tried something innovative. (I don't agree with this one, I'm just trying to prove a point. Both controllers look great.)
TV - The only thing I hate more than TV is cable TV.
Storage Space - Playstation lets you use actual hard drives where as with Xbox you can only use USB HDDs, which are slow to transfer data. Not a viable solution for playing games from.
Games - All the Xbox games look like they were aimed heavily at dudebros who like explosions, where as Playstation actually had some variety in their line up. I love indie games, and I'm much more interested in them than the AAA titles. Not to mention Sony has been building great relationships with developers, while Microsoft just buys exclusives.
Now, I'm not saying you're wrong by any means. All I'm saying is, it's very easy to rationalise one way or the other.
