The Playstation 2's highly regarded DualShock 2 controller was considered by many to be the best videogame controller of all time. So when you've got a winning design there's no need to change anything. However, because of a legal battle with Immersion over rumble technology, Sony was forced to offer their Sixaxis controller without rumble. The Sixaxis had the same Dualshock design but it felt too lightweight and cheap. Thankfully the lawsuit has been settled and rumble has come back to the Playstation.

For the most part, the DualShock 3 is almost identical to its PS2 precessor. But it has all the features of the original Sixaxis controller in addition to rumble. The controller is still wireless, can be charged by plugging it into your PS3 (or PC), rumble is compatible with all PS1 and PS2 games, and the PS3 supports up to 7 controllers at the same time via bluetooth. Rumble in the DualShock 3 seems more responsive in regards to the location of its vibration depending on which side you get hit on during the games. I don't know if this is something in the design or if it's the developers doing it for the games but I welcome it.

All in all this is currently the best designed controller on the market right now. The PS2's DS2 was incredible so "if it ain't broke, don't fix it" applies here. I'll be enjoying rumble in my PS3 games from now on.
