When I look at 3D for some reason I just don't feel that well. Some people do tend to get dizzy when seeing in 3D, so it would be good for the people who get dizzy to just use their old DSs or just turn off the 3D.
I don't see whats so bad about the 3ds being $250. I mean, an ipod touch is 200 (or 300 for 32 gb) and the 3ds can take 3d pictures, play music, play 3d games, has great graphics, has a longer battery life than the ipod, and will eventually be able to take and watch 3d videos.
