Firstly, I must say that I am very pleased with the time it took the controller to get here. The item was shipped on Friday, and arrived on Monday. I guess Mississauga to Port Colborne isn't a huge distance, however, when I ordered The Orange Box from Amazon, it took 3 days. 1 day, with super saver shipping for the controller. Very pleased indeed. :)
As for the controller, it's basically the regular SixAxis PS3 controller with a vibration function included. It's a little heavier then the regular controller. Other than that, not much difference. The rumble (which I have missed since PS2's days) adds what was missing from some already great PS3 games. I will be playing Metal Gear Solid 4 through again just to see how different it feels playing with rumble enabled.
Looks like Sony finally saw their mistake. Please don't do it again. Keep the controllers just the way they are.
