My very first sentence is about how people have a huge variety of opinions on 3D in general. And to be honest, before this article I was not a huge fan of it. After writing it, my opinion has changed quite a bit overall. You have to remember that this type of 3D is not really designed to have things pop out of the screen as much as it is to add visual depth. I think this is what a lot of people don't realize due to most of the marketing done on this technology. While i am not what I would consider a die-hard 3D fan now, I would say I am a fan of it in several circumstances. Like i mentioned in the article, not all games greatly benefited from being in 3D, those that did however it added a great deal of visual immersion.
The only 3D movie I saw in theaters was Avatar, and had to leave a few minutes in due to getting a massive migraine from it. My biggest fear before starting this review was that I would end up with migraines and be unable to complete the review. I have had several 4-5 hour sessions on the 3D Vision kit (many more shorter) and have not experienced even the slightest headache as I did with the polarized lenses common to movie theaters. Now this is me personally and may not be the same for everyone.
You are correct on a few things, it is something that you need to see and experience to see if you like it. There is a lot of new technology like that, several years ago people didn't think an HDTV was worth the extra money. For many, the investment for 3D vision is relatively minor. Gamer's are starting to buy 120hz screens for non-3d use, many have NVIDIA graphics cards already so that makes 3D vision a fairly minor additional investment.
Maybe 3D Vision isn't for you, maybe it is, the point of the article was not to convince anyone that 3D was absolutely for them and was definitely not 'directed at children who would never, ever admit to their friends or family that they really don't like, cant see of physically suffers from 3D media in general'. The main part of the article was to show how far the 3D vision experience has come in 2 years. Convincing anyone that a visual technology is something that they need when they are unable to see it is silly. Trying to show people that if given the chance they should see the technology for themselves however, is not.
TLDR: Don't make decisions solely based on what you read on the internet. Try to see things for yourself and make your own decisions. NVIDIA uses a technique for 3D that in most cases should not cause eyestrain or headaches like polarized glasses at movie theaters do to some people.
