All but the Vita. PS3 is in the living room, mostly played by the kids and wife, and used for Netflix. When we can pry my son from Skylanders, that is. Wii is also there, wife's favorite system.
My 3ds gets regular play, I love it. The 360 is in the man cave, hooked to the big TV. Usually has Netflix on, buts sees plenty of game time from me. The 3ds and 360 are my current favorite systems.
I also have a PSP, modded for emulation. Sees some play, not much. That's part of the reason for not buying the Vital yet. Thar, and rediculously overpriced memory cards.
