Yesterday was the four-year anniversary of the US launch of the DS. What was your opinion of the DS back in 2004? None of us knew back then what it would become today; we expected GBA-level popularity at best.
Were you totally lined up for a system on the first day? Did you wait until Christmas? Until Kirby? Or were you not drawn into the DS life until the Lite appeared? Whenever you got into the DS, we're glad you did, because we doubt you would be part of our community otherwise.
As for me, what finally sold me on the DS was Castlevania: Dawn of Sorrow. Luckily, the system got even more awesome after that!
