The Sun didn't come to any conclusion that Nintendo hasn't already warned people about in the first place.
"Don't play in 3D for very long periods of time"
When you've been playing the 3DS in 3D for about an hour, turn it off and continue playing. It's as simple as that. It's understandable, though, that people who can't see 3D or get headaches very quickly with it wouldn't want to pay $250 for the system. The system itself isn't useless without using the 3D (It's obviously the best Nintendo handheld device even without it), but people are paying extra money for the 3D effect, so it's fair for them to wait for a price cut if they don't care about the 3D for whatever reason.
However, people who complain about the headaches should seriously not forget about the SLIDER. I realize some people may still get headaches, even when it's set to a lower or more comfortable setting, but there are a lot of people that I've talked to who were getting headaches because they had the 3D on max, and once they used the slider to tone it down a bit, they stopped getting them completely and could still see the 3D effect very very well. The entire reason the slider is there is for these very same people who are complaining, and yet many of them aren't using it properly. I can guarantee that at least 50% of these people you've heard complaining would stop getting headaches if they used the slider to find their comfort level.
