First of all, there is no such thing as a perfect game controller.

As soon as you optimize things for one type of game and/or one type of player it will be suboptimal for other types of games or players.

I have been playing video games since 1977 and have played or owned almost every game system since the Atari VCS 2600. I have used the stock controllers, many aftermarket controllers, and even made and played a few custom controllers and in the few hours since my Dualshock 4 arrived I have held it in my hands, (carefully) opened it and looked at the fabulous internal design, and used it with my PS3.

In my short time with it and mentally comparing it to everything else I can honestly say that this is the best, most comfortable joypad so far (the Valve Steam controller is in Beta still, so it will be awhile before this promising looking device is out).

Second, I am not, repeat NOT a fanboy (O.K. I was one in the past, first Atari, then Nintendo, and even championed the ill fated Dreamcast for a bit) and even prefer the X-Box controllers for some games.

It was not about placement of the d-pad and left thumbstick, but more that I have big hands and the Dualshock always felt too small for me, the handles too short and the thumbsticks too close together.

I did get used to it and liked everything else about it. Thankfully, the Dualshock 4 fixes these problems.

Even putting aside the light bar, touch pad, and speaker (all of which I am looking forward to seeing implemented in interesting and innovative ways) the Dualshock 4 is the most changed, most improved controller since the original Dualshock improved on the original Playstation controller (edit: actually, thinking further back, the SNES controller was a HUGE improvement over the NES controller; which often caused hands to cramp and bruised thumbs, leading to the term "Nintendo Thumb").

In fact, the most interesting change is that "Dualshock 4" appears nowhere on the controller (I guess there was no good place to put the name).

I did take a few pictures if the internals while I had it open and will post some in customer images (there are only 4 #0 Phillips head screws, but there are 4 snaps/catches holding it closed, 2 in front between the thumbsticks and 1 on each side about 1 inch from the shoulder buttons, making it not too hard to open). I may post an update once I've actually used it with my PS4 for awhile.
