What is the need for it? Does it satisify a problem people have that has not been addressed?
Other technologies that have been incorporated in cell phones have addressed needs, such as not carrying multiple devices. That is why phones now have 3.5 mm headphone jacks and cameras. There is no real need to have a device display 3d. The technology is still in its infancy and there are no industry standards so currently having the ability to us it is gimmicky.
What's the need for 4G? For Bluetooth? For GPS?
It's just another option.
As for there being no standards - ummm - well, no more than exists for 3D HDTVs, BD players and disks. You can take the Evo 3D, convert your legal 3D movies using Handbrake (just like is done for 2D movies) and they play fine on the device - and can output 3D via HDMI to a compatible TV.
It's glasses-free technology in its fourth generation from Sharp - hardly new.
And it's not made to be viewed by 80 people at once - it's designed to be viewed by one person, looking through a phone display. From the sweet spot. Exactly the way an audiophile listens to music or a videophile watches their big HDTV.
Viewed properly, it's a eyestrain-free experience, complete with depth or things popping far out from the screen (up to the movie producer).
And while the popular dialog tries to establish that 3D is for the lunatic fringe, the truth here is that smartphone surveys show that 3 out 10 prefer 3D, 3 out 10 think it's a waste, and 4 out of 10 don't much care if their new top-end phone has 3D or not, because they already don't expect to use all of the features anyway - so long as there doesn't appear to be a cost burden.
Taking last year's Evo 4G vs. the Evo 3D, the new model packs a dual-core processor, twice the ram, 4 times the rom, a higher resolution display, phenomenally better battery life - at the exact same price as the 4G (adjusted for inflation, it's actually cheaper).
That's been showing itself in the forums to satisfy that 40% nicely who won't use the 3D feature.
So, while the 30% of you thinking this is a gimmick are certainly right because opinions are never wrong (I actually believe that, that's not sarcasm), please notice that not all opinions (on either side of this fence) are fully supported by facts.
The facts are that the facts can be skewed to show 70% aren't in to 3D or that 70% are ok with 3D - but in the end, the lovers and haters are about an equally sized group and each group is outnumbered by the don't-cares.
As Gmash points out, this old chestnut keeps cropping up. Rather than close this one, I'm going to leave this open as the thread recurrence simply indicates that it's something people seem to want to hammer out, and that's good enough for me.
And with that, off comes the mod hat, on comes the user hat.
Rather than gimmick, I think it's a novelty. I would never, ever want to see The Maltese Falcon or Good Night and Good Luck in 3D. However - I have seen a few amusing things on YouTube in 3D and I'm no worse for the wear.
Some say 3D will die out (again, after all, it's been around before), while others say 3D is simply part of the natural evolution of display technology. That - I have no clue, time will tell.
I do know that I don't use Bluetooth and I do know that no one really makes my ideal phone (and probably never will due to costs). So, in today's market, I've not found a better phone for me, I'm totally happy with my purchase and the device.
And they threw in 3D along with Bluetooth, both of which are really just novelties to me - but didn't seem to increase the cost compared to competing models on other carriers.
