My 3DS stopped charging after about two hours or so, so I've spent about an hour with it. First impressions:
- Thankfully, no headache or eyestrain so far. I was particularly worried because I'm a bit flu-ey at the moment. I took it very easy with the slider, starting very low and nudging it up slowly. Not past the middle-mark.
- The 3D is a bit 'strange' though and takes a little getting used to. I have felt my eyes making strange movements, and strange-feeling focus shifts from time to time - particularly when looking at text, or between the environment in Pilotwings and the pilot himself. It does feel like more is going on with my eyes/head, but we'll see how it goes.
- The screen takes on some - IMO - slightly compromised qualities with 3D turned on. Or maybe it's just me. But it looks different in 3D mode, some aliasing in PW looked...different...some parts of the screen almost looked 'greasy', there's a change in colour.
The analog pad feels fine, nice amount of tension in it. Haven't had much chance to explore much else yet, will sort out my friends code and post it in the relevant thread soon.
