I keep on seeing these guys going on and on about graphics, but if i'm not mistaken the most powerful machine has never won a console/handheld war.
Megadrive outsold the Snes
Nes Outsold The Mastersystem
PS2 outsold both Xbox and Gamecube
DS is outselling the PSP
GBA outsold the N-gage
Playstation 1 outsold the N64
The original Gameboy outsold both the Lynx and Game Gear.
Maybe this was why Nintendo chose not to up the Wii specs?
