I voted Wii back when this poll was first made. Sure the other systems have some big advantages such as Blugay and hd gaming, but the games on those systems don't interest me. The Wii is cheaper, the games are reasonably priced, it has a bunch of stupid games that are great fun with a few friends. It also has the traditional Nintendo games that you just can't get anywhere else, and as a NES, SNES, N64, Game Cube, Gameboy, Nintendo DS, and Wii owner I appriciate the Mario games. I also grew up with the NES and SNES so playing those and old sega games in the virtual console is pretty cool.
I'm sure you guys can counter my arguments, but that isn't the point, I was just explaining MY reasoning for voting Wii.
