My set-up isn't as classy looking as his, but I'm not wanting for many systems, either:
What you see in that picture:
On the first shelf, starting with on the left side of the T.V., going right and top to bottom: Sega Power Base Converter (Plays Sega Master System games on your Genesis), GameCube, Dreamcast, Nintendo 64, PlayStation (PS1), Sega Saturn, Super Nintendo, NES, Atari 2600 (since this pic was taken, I've traded in the Jr. model you see there for the classier wood-grain model)
On the smaller shelf beside it: PS2 Slim-Model, XBox (Original), Spider-Man & Super Pac-Man T.V. Games.
In-front of the shelves: Sega Genesis with a Sega CD attachment and a Pong-clone system from the 70s called The Wonder Wizard.
Not in the picture is a Nintendo Wii and XBox 360 that are hooked up in the living room. Plus there's my trusty PC.
Handhelds (also not in the pic): Game Boy (Original), Game Boy Color, GBA-SP, 3DS XL, Game Gear, Neo Geo Pocket Color, and a Milton-Bradley Microvision from 1979.
So I'm pretty happy with my system. Though nicer-looking shelving is needed.
