Personally, I absolutely love my cosmo black Nintendo 3DS. The 3D effect is good, it feels really good in my hands, and I can play 3 different Zelda games on it. What's not to love?
Games I can't wait for:
MGS3
Animal crossing
Paper Mario
Kingdom hearts
Monster hunter
Kid Icarus
Super Mario 3d land
Mario Kart 7
Fire Emblem
Bravely Default: Flying Fairy
And the list goes on...
(hoping for Majora's Mask 3D!)
