Forget the DS comparisons though, the GBA is kicking the 3DS' butt pretty good too.
Last year represented the lowest shipments for Nintendo handhelds since 1997 or thereabouts, which is before the GBC launched.
It's doing OK, but it represents an alarming collapse in Nintendo's handheld dominance. Kids and casuals are clearly flocking away to tablets/phones.
And this year is down from last year again.
