What's the lowest selling system you own, was it worth it, and why/why not?

PSP. I didn't really play much on it, so no, it wasn't really worth it. Its battery got bad too, so I think got rid of the whole thing (or maybe just the battery, if that's even possible) - regardless, I don't currently even have a usable PSP anymore.

I think the only thing I really played was Metal Gear Solid: Peace Walker, and I didn't really get very far in it either. It was good, but I guess the controls felt like they could've been better with a proper controller. I have the impression that I also started Metal Gear Solid: Portable Ops but played even less of it, possibly because of either terrible camera, poor controls, or both. It's quite sad that Portable Ops isn't available anywhere else, but at least Peace Walker got ported to other platforms.

It felt like a fun system, but I just didn't get into the games. Later I've also come to realize that playing on portable devices doesn't even feel like a great experience to me, which is a pity, but it is what it is.
