Share button.
If it was a, maybe context sensitive, screenshot button, sure!
But no. Share. Button.
Hell, they already had a Start and Select, why not use one of those? From the looks of it, they literally just converted "Select" INTO "Share". Only difference is it sounds more stupid and can't be used in an actual gameplay context.

Touchpad COULD be useful, but it'll also drive up the cost of the controller and quite frankly it sounds silly and like something I would never use much. Maybe I'm wrong since I've not actually used it, but I've used a DS plenty, and mixing buttons and touch screens doesn't work too well in my experience. Just ask TWEWY, and that's when I can see where I'm tapping and the button controls are simple.
Also, it's silly and they've only got it in because they want to copy Nintendo.

Wireless, ♥♥♥♥ batteries. There is nobody here that has not felt the frustration of goddamn wireless controllers and their goddamn batteries. Rechargable batteries can still die, and if you're going to have it plugged in 24/7 anyway why not just get a wired controller in the first place? No chance of signal derp-ery, no chance of batteries dying, hell, cheaper to make. I mean, if your TV is an assload of distance away from where you sit, sure go wireless, but I've never found it much trouble to move closer anyway.

Ignoring those problems though (wireless is negotiable), I really like the look of it. Looks like a pretty good controller, both to use and look at.
tl;dr: The new features are silly ideas, and I like wired controllers. Aside from that, tenoutaten.

AlsoThey literally shunted the Start and Select Share buttons far up and to the side to make room for it.
It's in the way.

WAKE UP AMERICA

be real with me sothe, do people really think we're being run by lizards or is that a whole poke at conspiracy theorists

also

you're being serious right.
tell me you're not being serious.

Sssh don't tell any1.

He said a while ago that it was a joke.

THKU I see you've done a lot of research on the topic, by which I mean you looked at that picture. Good job. Start and Select have been combined into a single Options button on the top right. The Share Button is indeed context-sensitive and can either record video or take a screenshot when pressed; it is designed to not interfere with gameplay, as this is important in un-pausable multiplayer games.

The touchpad's possible usefulness is not limited to games. A lot of people speculate it is designed to make it easier to navigate browser UIs, especially considering that Sony are pushing towards larger sharing/multimedia integration. Using a controller to navigate the web isn't as nice as having basically a clickable laptop trackpad.

"There is nobody here that has not felt the frustration of goddamn wireless controllers and their goddamn batteries." Wrong. You've clearly never used a PS3 controller for extended periods of time. Those shits are immortal. I've played for 12 hour periods with them with no problem. Even when they give you the WARNING SUPER LOW CRITICAL BATTERY message you can play for pretty much another hour with no problem. Fully charging it takes about an hour and can be done using any USB port. Signal derpery? I've controlled my console from distances of ~30 feet without any latency or inaccuracies. No idea what you're talking about.

tl;dr > ITT HKU predicts the performance of a next-gen controller based on a single picture and his experience with what I assume to be shitty third-party wireless controllers. Get off the MadCatz and switch to a Dualshock 3 for a try, since it's the closest thing to a Dualshock 4 available right now.

Start and Select have been combined into one button?
Now there's a Share button with no gameplay purposes?
Thank you for confirming my point.

I don't want to use a gaming console for multimedia bull♥♥♥♥, I have a computer for that. A computer that has a keyboard and mouse, instead of a Dualshock 3 with a touchpad. If it's there to make the non-gaming experience better, then it makes a terrible experience (with no touchpad or keyboard) into a sorta less terrible one (with a touchpad but still no keyboard).
♥♥♥♥, just pull out your laptop and sit it next to you while you play.

Also no, I've not used a PS3 controller. If they actually are as hardy as you say, I'll slightly retract my statement, but you still have to charge them at some point, and if they die or start dying while you're playing you'll want to break something. Especially if your normal seat is 25 feet away from the TV like you said, and you need to go sit way up close to charge it.
Also, signal derpery, yeah that was really just a hypothetical. Technically, there COULD be some interference from god knows what, but let's be honest it's not gonna happen.

MadCatz is terrible and you should feel bad.
That said, I've used Wavebirds, Wiimotes, shitty 360 controllers, all have the curse of the battery.

MadCatz is too cool for all of you

I own this controller so I would know

As we know, there is not a single person in existence who plays only console games. When combined with the fact that the entire gaming customer base unanimously agrees that a mouse and keyboard are always better and easier to use than a controller, it's obvious that the Dualshock 4 sucks because it has a share button.

...

90% of people on social networks first started using them on a device with a keyboard (a very conservative estimate). Chances are, they still have access to that keyboarded device. And find it more convenient to type out a status update or browse ♥♥♥♥ on IT, rather than on the console.
Social Media integration on a console; fine. Stupid, but fine. Trying to make the PS4 a primary source of usage for it? Lolno.

There's a very large difference between playing a shooter with a console controller vs keyboard and mouse and using the internet with them. You really, really can't compare them.

And as I've said, Dualshock 4 looks amazing, with the exception of the nonsensical Share button and the stupid touchpad.
Share button isn't even a huge problem, it just doesn't make any sense.

The system comes with dedicated video capture. It makes perfect sense to have a button that immediately makes use of that rather than having to stop your game and wade through a menu. It's the equivalent of having FRAPS open and hitting F9 to start recording. How does that not make sense?

I don't remember and don't care to browse back through the thread to see if someone posted an update on the RAM stuff, but I found the tech specs and they are in fact using x86-64, so my point on that matter is now no longer applicable.
Touch pad still seems silly to me, but that's a matter of personal preference (I thought the original hueg xbox controller was super comfortable).
Large die still bothers me.

Because they literally took the perfectly usable Select button and chopped its balls off to become a Share button. Why not say "Hey, we have video capture! You know that Select button? You game developers could totally use that for toggling it! Here, have some APIs and documentation!"

And they put it on in the first place to push this whole social media integration thing, which doesn't work well in the first place because crappy controls for it and pre-established market of non-dumb usage methods (smartphones, computers, tablets, etc) mean that nobody WANTS to use it.

You mean you don't want to talk about MadCatz?

Anyway I'll just throw my two-cents in, or rather my harmless opinion
Touchpad will be useful in navigating menus, possibly unique features in games, better quicktime events than just button mashing
Share button seems appropriate for the new features they've given us, I suppose if that was a dedicated feature rather then a third-party feature I'd like to have the option at my fingertips
I never really saw a use for the back button on the Xbox controller so I just need a start menu button

You really need to stop using this kind of argument. Making blanket, hyperbolic statements in which you project your opinions on everyone else isn't really proving anything. Let me clarify: you don't want to use it. That doesn't mean that nobody wants to use it. In fact, it doesn't even mean that most people don't want to use it. We don't actually know that yet, and we can't possibly know until this thing is a tangible product and not just a picture of a controller.

Personally, I'm excited to see a console that lets me natively take videos of games I'm playing rather than having to shell out for an expensive capture card. Forget the social media part — obviously, that's "hip," and it's what corporate bigwigs have been trying, and arguably failing, to do with consoles for years. The actual ability to quickly take videos is the interesting part, and that's what the share button does.

From the simple point of view of the controller (which is the part we're talking about here), they've replaced an underused button with a quick way to do something more useful. I can't think of the last time I actually used the select button. Is there really such a deficit of buttons on a DS3 that changing the functionality of a single, seldom-used button is going to be seriously detrimental?
