I have the 3DS and am very prone to headaches. Honestly, the 3D does bother me unless I am holding it in the exact right position. However, you can easily turn off the 3D or turn down its effects. The games on the 3DS are great. I would recommend looking at the games for the 3DS and seeing if there are enough games you want to play to upgrade.
Jonna N. asked, “I love my Nintendo DS, but is it really better to upgrade to the 3DS? I'm a little worried about getting a headache from the 3D. Advice, please?”
I would recommend signing up for the first box with the promo codes that are usually available. These typically range from a free box or a box for a penny (just pay shipping). However, I would recommend trying out the polishes before you consider buying another box. The bottles are small, and the polish formula is not for everyone.
