Honestly for color I just go with black most of the time, it never ceases to please me when the newest fad color comes out and this way my handheld does not look like a child's toy. Also white is acceptable too, as is silver, which isn't out yet for the 3DS, but I prefer black as it doesn't get dirty and stained like white does. The purple is nice but it just reminds me of the purple GBA which was ugly and non-spectacular, also the godawful purple gamecube, thank god I got black then. I don't see the point in selling your handheld and buying a new one just to get a different color since it doesn't offer anything different in the functionality department.
