If the purpose of the list was "memorable" not including some of the joy-sticks for flight sims in the mid-90's is a glaring omission especially considering the inclusion of the steel battalion rig.
I'd remove the first PlayStation controller from the list as the dual shock (and the line of successive controllers based on it) is sufficient.
This list appears to be written mainly from the console perspective ending with the PS1 and N64. The Dream Cast controller, while not as successful as those 2, is as memorable:
The Xbox original "Duke" was memorable for all the wrong reasons:
Lastly the Rock Band crazy of the 2000's might have warranted the inclusion of that set along with the Guitar Hero controller:
The PowerGlove really only was for the folks who could afford the thing. Maybe not as memorable as the controllers that actually came with the consoles. They covered PC controllers and I think the sidwinder joystick line was quite memorable.You forgot the best controllers.

The POWER GLOVE BRO!
