That's not rumble, it's the controller elves beating out the morse code-like signals on their tiny war drums that their distant cousins, the console gnomes, detect and translate into instructions for the game people to act out on your screen.

Ahhh, the SIXAXIS, the launch controller of the PS3. I actually forgot about that thing, I replaced it ASAP. Sony's 'official' excuse was that motion control was the future, and the rumble feature would get in the way of the amazingly precise and awesome motion control that was utilized in a small handful of games and were pretty universally hated (seriously, the balancing sections were the worst part of Uncharted. Thankfully, that dropped that idea before 2 came out. Even worse were the Ratchet and Clank minigames.)
Somehow, in the end they managed to find a way to put both features in control after all (for only $60!), and the Dualshock 3 became standard. Still had crappy sticks though, I never could get used to precision shooting in any game that used it...
Right now, I'm in the process of figuring out whether to go for the PS4 or XB1. I will admit, my biggest fear of the PS4 is that we're going to go through the same process with the touchpad on it's controller that we did with the motion controls; a bunch of first party titles using it for arbitrary, unfun minigames and simple commands that just slow everything down. I'll admit I have the same concerns about the XB1's kinect integration as well though, that crap was terrible in ME3. At least they had the decency to let you completely turn it off.
