You know, when Nintendo first showed off the Indigo Cube, I hated it. Over time, it grew on me, though. I still bought a Jet Black, but almost went with the Indigo.
This is a pretty awesome color. It's similar to the new Monster Hunter 3G system just without the special MH3G artwork and such. Man, I would really like to pick this up as I'm not a huge fan of the Aqua Blue I got on launch day (it was the LAST 3DS at the store), but I can't justify buying another Japanese 3DS. If anything, if I pick up another unit, it will be a US one.
