I just noticed that naz mentioned me, so I'll post my setup here.
This is my living room:

I've got my 26" Polaroid HDTV, with a GC, Xbox, Dreamcast, and PS2 hooked up. The shelf on the right is filled with games. My computer is also hooked up to the TV, and when I get a wireless keyboard/mouse for Christmas, I'll be able to surf from the couch or comfy chair. I've also got a Cobalt Flux for DDR, but getting it to sync up with the new TV hasn't been fun.
This is my bedroom, with my older systems:

Here's my N64, NES, Saturn, and Genesis. I don't play these a whole lot, but it's still nifty to have them set up. There's a Virtual Boy in the closet, but I don't have a place to display it.
Jam it back in, in the dark.
