One of the main concerns that has been brought up relates to every day use and the 2D/3D toggle switch.
The User Interface (Sense 3.0) is not in 3D (It does not pop out of the screen). The standard functions of the phone are in 2D just like every other phone. The 2D/3D toggle switch is for taking pictures and recording videos.
The HTC EVO 3D was released on the 24th of June, 2011. The phone is $199.99 on contract and $499.99 off contract.
The FCC has released some documents (2 Jun 11) with the hardware used in the EVO 3D: http://androidforums.com/htc-evo-3d/335824-3devo-pre-release-miscellany-16.html#post2769741 More info about the hardware and exact specs from the FCC is also being discussed in this thread as well.

Using geometry, we can also arrive at the final dimension - or you can just use this handy calculator, like I did -
Screen Aspect Ratio & Dimension Calculator
Evo @ 15:9 w/ 4.3" -> 2.21" x 3.69" -> Area = 8.16 sq. in.
E3D @ 16:9 w/ 4.3" -> 2.11" x 3.75" -> Area = 7.90 sq. in.
Evo dimensions verified by my 10ths ruler - hehehe.
Total area difference - probably about two of these:

Hey guys, tried to find this myself, but didn't turn up anything conclusive. So any help would be appreciated
1. Can the Evo 3D use data and voice simultaneously?
-Not like AT&T - if you have WiMAX (4G) or wifi available, then yes - if just basic 3G, then no.
2. Does the Evo 3D have a notification light?
-Pretty sure.
3. Can I turn the screen to 2D out of preference or to save battery?
-The screen is 2D by default and only switches to 3D (automatically) when playing 3D movies or games or viewing 3D pictures.

Benefits of the camera:

Yeah, this pretty much sums it up.
Having the shutter where it is allows you to grip the phone well AND press the shutter button with ease. This will reduce hand shake a lot which means higher degree of success for those low-light shots. I have a hard time using the touchscreen shutter button, especially when I'm trying to grab a quick shot. With a dedicated shutter, you also know exactly where the shutter button is with your finger, so you can focus on keeping your shot composed.
And Cavemansol mentioned being able to adjust your composition once you've held down the shutter button halfway. Can't do this on current phone cameras. There's no halfway on a touchscreen
So yeah, the focus lock is a great tool for making your photos more interesting. While I don't like "rules," check out the "
rule of thirds" as it applies to composition.
And it's unknown if repeatedly half-pressing the shutter will get the camera to choose a different focal point. Canon tends to do this with their dedicated cameras.
It's a great feature if you take pics with your phone.
3D capabilities:
http://androidforums.com/htc-evo-3d/345384-3d-pop-out-clarified-violations-lead-discomfort.html
...Commonly, the distance between cameras (aka the stereo base) is set to the human interocular distance (distance between human eyes), which is about 2.5". But there's no real reason why this needs to be enforced; it really depends on the scale of your subject. If you're taking a picture of insects, your camera lenses should be much closer together. If you're taking a picture of the grand canyon, the cameras should be very far apart. Again, that article above talks about why you may want to use cameras that are further apart. But a moot point for E3D since we can't adjust the cameras. But given that the Evo's cameras are kinda close together, the best 3D shots will be with subjects closer to the screen.
Onto the discomfort.
My source tells me that pop-out is actually not very desirable for two reasons:
1) it causes eye strain due to the need to focus on a point close to the eyes (cross-eye). Prolonged cross-eye is not comfortable.
2) when a pop-out object is cropped by the edge of the screen, our brain freaks out because it conflicts with reality. The object should appear in front of the edge and not be cut off. This is considered a violation of good stereoscopy and should be avoided.
Another violation is an exaggeration of depth where the distance between stereo images exceeds the interocular distance. This isn't going to be a problem with the Evo 3D's images, but this is much more common in a theater. Film producers sometimes push the limit to try to give the scene maximum depth by spacing out the parallax images. This can trigger instant headaches. Also if you sit too close to the screen, the problem becomes amplified.
He rattled off a few more violations that I can't recall, but basically he says that the violations are what make 3D gimmicky, and it's also responsible for the discomfort and inability to see in 3D for some subset of the public. When the rules of stereoscopy are obeyed, the results are spectacular and comfortable to view, because they simulate depth realistically.
Performance (over/underclocking) and battery life:
http://androidforums.com/htc-evo-3d/331783-underlying-tech-evo-3d-qhd-3d-dual-core-smp.html
If all things were equal, you're right - no such thing as a free lunch - so running faster means using more juice and lots of it goes to wasted heat.
In this case (for Evo users) - it's using a more advanced manufacturing process where the stuff in the SoC (transistors, etc, etc, etc...) are smaller and closer together - lots smaller. Smaller stuff takes less power to run than the same stuff when bigger.
So - in this case, if you put an Evo side by side with an equivalent made with the newer process, the newer one will be more power efficient - enter the Thunderbolt. In that case, tho, they made the battery smaller, so on that one, there wasn't the big gain in advantage.
In this case, the silicon is made with the smaller manufacturing process (45nm vs. 65) _and_ the battery is bigger.
The SoC - the MSM8660 - in the E3D does indeed have a dynamic clock like the Evo (it's pretty much the rule now).
And - we tend to expect a dual-core to run any given process at lower speed than if run on a single-core (providing things are optimized sufficiently for dual-core use - we won't know that until it's here).
Downside - higher resolution. With more dots to update on graphics-intensive tasks, more processing is required at the end. More pixels also mean more control transistors on the display itself (by definition for LCDs).
There are just too many factors to know in advance if this will act same, worse or better than an Evo on power.
It could be way more power-efficient - or it could be worse - we'll have to wait and see.
Benefits of a dual core processor:
http://androidforums.com/htc-evo-3d/331783-underlying-tech-evo-3d-qhd-3d-dual-core-smp.html
Jensen nailed it. In the Android environment, you can't do any process intensive tasks on the foreground thread which processes GUI, otherwise you will end up with super-unresponsive apps. By this nature, you are pretty much forced to go multi-thread. As long as the version of Android used in the phone is SMP enabled, both cores will work at these threads independently, hence experiencing performance gains.
It is true that most apps of today won't utilize both cores to 100% all the time since the workload isn't split symmetrically, but still, a benefit is a benefit. Apps like Smartbench 2011 (I am the author) does symmetrically split workload within the app - I currently split the workload equally into 4 threads hence Smartbench 2011 will utilize 100% up to 4 cores when they become available.
Developer developments:

It means developers can create apps that are Sense-like.
The HTC OpenSense SDK will allow developers to harness software and hardware innovations on HTC phones to develop more deeply integrated mobile apps and experiences. Altogether, you'll have access to documentation, sample code, APIs and more importantly, the support and inspiration of the HTCdev community.
The Common Controls:
As a part of the latest Sense UI framework, HTC developed a suite of customized controls that Android application developers can use to create a Sense look and feel within their applications.
That means Sense dialog boxes, buttons, progress bars.
Be among the first to access the latest HTC technology with the Tablet pen API and Stereoscopic 3D display API and sample code.
That means access to develop 3D stuff - jump started with samples of working code.
~~~~~
It means devs get to use a common code with Sense - if the feature works in Sense, it'll work in the new app, same way.
Memory:

ROM vs RAM vs eMMC
In the old days, we had RAM - random access memory, meaning you get to any memory bit any way you liked. We still have that.
In the old days, we had a kind of chip called ROM - read-only memory (with random access) - and the thing with ROM is it remembers when the power is off (RAM forgets when the power is off). A ROM could never be written to once burned at the factory. Then we had various programmable ROMs, where you could write to them for some limited number of times, but you could read them to your heart's content - these, we used for PC BIOS for those of you familiar with that.
Years ago, they invented a new kind of memory that they called flash memory. Any of your USB sticks or SD cards of any kind - all flash memory. If you recall, advanced smartphones, MP3 players and USB sticks all started hitting the shelves at about the same time - because of flash memory.
The thing we call ROM in modern smartphones isn't ROM at all, it just acts like ROM because it remembers when the power is off - it's been flash memory all along.
An SD card is a type of multi-media card (MMC). Recently, someone bright said - hey, we have one type of interface to the SD card and another type of interface to this stuff we're telling people is ROM, but it's all just flash memory. How about we make the ROM thingy with the same interface to simplify things? Good idea, so they did it.
And that's the eMMC flash memory aka ROM in the 3vo.
So - in that one Samsung package, there's going to 1 GB LPDDR2 RAM and 4 GB eMMC - or you can call it 1GB RAM / 4GB ROM.
(Fun fact if you've read this far. Flash memory is factory-built with one of two types of logic - NOR (not or) or NAND (not and). The flash we use in our phones is the nand logic type. So when you hear rooters talking about the NAND bootloader or making a nandroid backup of their rom - it's all about using slang for the actual type of flash memory the phones have.)
And on that odd distribution of RAM - if there's 256 MB squirreled away inside the 8660, Qualcomm isn't talking, so I don't know. Or the actual MCP will have 1GB. Either way - it's going to have 1 GB RAM, imo.
btw - LPDDR2 RAM and LPDDR2 SDRAM are the same thing, call it either way you like, I chose the former because it's 2 fewer characters to type.
