When Sony's PlayStation 3 came out in late 2006, much was made over the fact that the new Sixaxis wireless controller that shipped with the system didn't offer any force feedback--or rumble, as the vibration feature in Sony's earlier DualShock 2 controller (for the PlayStation 2) is often called. Sure, the whole poor-man's Wii motion-sensing thing (Sixaxis) was somewhat cool, but Playstation aficionados and gaming purists were disappointed that Sony was forced to leave out the rumble because it was involved in a patent dispute with Immersion, the company that developed force-feedback technology.
The good: Wireless PS3 controller with rumble support; slightly heavier, which gives it a bit more heft than the feather-light Sixaxis controller; rumble function added to many existing games via downloadable patches.
The bad: Somewhat overpriced; doesn't come with a USB cable for recharging; rechargeable battery isn't removable.
The bottom line: While it costs a bit more than it should, the DualShock 3 adds the rumble support that should've been present in the PS3 from the beginning.
