Its a bit wierd, People were fine with the design when it was the only option. Then the 360\Xbox S-pad came along and people started to hate the PS pad.
I mean dont get me wrong, 360 pad is great and so is the S-pad, and i understand the love for something until something better comes along, but what i find silly is how its gone to such a black and white place. Now something better has come along all of a sudden the PS3 pad is horrendous and steals babies for food. Rather than just being surpassed yet still be fine and useable.
Im actually of the opinion that the PS3 pad is better for most games, where as the 360 pad is better for just FPS games.
I've never liked the PlayStation pad, despite owning the PS2 and now PS3. Aside from a short while (original pad), it's always had a better competitor. It doesn't fit as it should, the sticks are in the wrong place on the pad and the triggers don't face the right way either.
They should have taken the opportunity with the PS2 to change it, and at the very least the PS3. They've tacked on bits just to maintain the design.
The ideal pad for me would be a cross between the feel/shape of the 360 pad and Gamecube pad. Wireless, a set of analogue triggers (that can 'click' like the GC pad). It should also charge via USB. Drop the Select button in favour of just a menu/start button and a home button. I suppose Six Axis controls could feature, though I can't think when I've ever used them for the PS3.
