Happy tenth Bithday to the BEST CONTROLLER EVER.

Well, it is my favorite, lol.   I'm certainly happy Sony hasn't changed it.  Sometimes, change is bad.  :)

I think it's functionality is unparalleled.

The only thing that impresses me about the dual shock is the fact that the joysticks also have buttons. Otherwise I far prefer the Gamecube controller. It fits in the hand better.
I have found it useful for playing roms on my computer though.

It also does pretty nice if I hold it in my left hand and mouse with my right for FPS games that support that. It's nice because I've got, lets see, Joystick, 3 primary buttons, and 4 spare buttons(5 or 6 if you also count the select and start buttons) that I can map keys to that normally are handled by the keyboard on mouse w/keyboard games. It's not quite Wiimote w/ nunchuck, but it actually has the advantage when it comes to sheer button number, which is nice since Mouse w/ keyboard tends to be button command heavy.

How could one controller design last 10 years, and people still be happy with it?

It's, of course, the Sony magic.
I don't have a DualShock 3 yet. I'm still playing with the crappy SIXAXIS.

Sony stuck with the, "if it ain't broke don't fix it" manta and it has done good.

 They did change it, the DualShock 3 is wireless, has the home button, has triggers, and SIXAXIS functionality.

Great controller. Does the job perfectly.

I'm sorry, triggers? did I miss something here? And I was referring to the design, more than the functionality, because they put in the analog sticks midway through the ps1 life cycle also. I think it is funny looking back on the boxes of ps1 games and seeing them boast "is compatible with the analog stick" or something like that.

This controller had loads of innovations. It was the first controller to have built in rumble, 2 analog sticks, and depressible analog sticks. Playstation's controller was also the first to have elongated handles and quad-shoulder buttons. It was great innovation, and it doesn't change in a major way because it is perfect (or very close).

And some punkass mentioned placing the left analog stick where the d-pad is and the d-pad where the analog stick is. Psh. I don't think so, that d-pad is the best for fignting games.  Or maybe the Genesis controller?

Yeah , its one of my favorites to :D Im happy that the PSP controller is similar :)
