I have 3 PS3's in my house and I don't know what to do with them. They work fine, they never get used and they pretty much aren't worth anything but don't wanna just throw them away either...thoughts?
Hold onto them, in the far far future their value may double to those wanting a PS3 in a hard to come by market, specially if any of them are the PS2 game playable consoles.
I want to say it's one to one, but in all honesty I'm a bit fuzzy there. I can recommend JoyFreak's sister site AdminIntel - Admin & Webmaster Resource where there are lots for people of varying degrees of expertise with development, you likely can get a far more precise answer there!
