1. I wouldn't buy it for the 3D either, but I didn't buy the Evo for the HD camcorder. If it ONLY had a 3D camera, then it would be a drawback. Having it as a one-click option makes it a plus, in my book. In addition, as someone else stated, you don't need a 3D TV to take advantage of it. How anyone can say that the fact that the phone has a 3D option is a bad thing is beyond me. It is a moot point at worst.
Ask XBox 360 users how moot their HD-DVD drive is. I would venture to say it sucks royally for them that the BluRay standard won out, rendering the HD-DVD standard completely useless.
The same thing can happen to the 3D feature on the Evo 3D. No, it shouldn't be the primary reason why anyone would buy this phone, but, y'know, it is called the Evo
3D so HTC must think it's an important feature. Plus, how much of the beefier processor, OS upgrade, etc., is required due to the implementation of 3D in this phone? The Evo 4G is still a top-of-the-hill beast in the phone world. Why the need to for such a significant hardware upgrade? Because they can? Maybe. Because they had to with the implementation 3D? I would guess that likely had a lot to do with it. I also think that the ridiculous hardware requirements for Sense 3.0 (or whatever version it will be) was an afterthought. Meaning, HTC didn't say, "Let's upgrade Sense to the point that it requires a giga-core processor that isn't even invented yet." The HTC developer department got the hardware specs from their engineering department, and then decided what features to put in the new Sense. That's my theory anyway.
3D in its current form
S (emphasis on the plural, because there are too many 3D standards out there right now) is working from zero standards. The TVs out there now are ridiculous -- none of them are the same standard. Some require glasses, some don't, some glasses require batteries, some don't, etc. And that's just TV's -- we're not even talking about the input devices yet -- cameras, disc players, cable, satellite, etc. It's just too new, and I laugh at all these people jumping head-first into it, because they have to be the first on the block to have it. In a year or two, I may end up with a 3D TV, but it will probably be because that's the only type of new TV sold, and by then a single standard will be nailed down so I won't be stuck with abandonware.
2. I will miss the kickstand as well, but I sure wouldn't let that small, easy to replace feature keep me from other more important goodies like image quality, speed, and upgraded user interface. Different strokes, though, I suppose.
Again, I highly suspect your speed from the new processor will be quickly negated by the bloated new Sense. If HTC is being honest that they cannot update the Evo to the new Sense because of it's "lowly" processor, then I can guarantee you that the new Sense is going to chew up most of your speed in the 3D.
But again, like you and others have said, different strokes for different folks. I came to the Evo game late, so that definitely explains a lot as to why I'm still happy with my Evo 4G. But if I was making my buying decision now instead of 5 months ago, I don't know if I would go with the Evo 3D, and that would predominately be due to the 3D feature for the reasons stated above.
