So finally got my 3DS yesterday, and I am quite happy with the system. It is well built, has a solid OS along with packaged software (though the camera really sucks, wish they would have put in better quality cameras, oh well). I found the right angle for 3D almost instantly, and have been playing Pilotwings Resort, which is a lot of fun. I can play it for 10 minutes are so with the 3D up all the way but after that I need to lower it a bit. When I got tired I noticed the 3D blurring a bit, and causing more strain, so I turned it off, which is to be expected. Really though I am quite happy with it, the 3D works great so far, it is quite amazing how much 3D has progressed.
