Just like the DS was a glorified GBA with a touch screen. Yeah.
i'm just gonna point out why you're wrong right here.
comparing the DS to a GBA is a fool's errand. the obvious difference is the inclusion of a second screen. another large thing to note is the game media. the DS uses a slim card as opposed to a game pak.
on top of this, the DS had built-in wireless and wi-fi. the GBA did not.
what you want to say, is saying the game boy color/game boy advance is a glorified game boy pocket/game boy color. the game boy advance was an upgrade to the game boy color, moreso than the 3ds was an upgrade to the ds, but it was a large upgrade nonetheless.
the game boy color was an improvement to the game boy color, but it was still essentially a glorified game boy.
the 3ds added: gyro controls, a slightly larger screen, a 3d top screen, some improved software which allowed wireless communications to be better, an analog stick, and the improvements to the dsi.
everything else is virtually game boy pocket/game boy to game boy color. at most, game boy advance.
the 3ds
is a glorified ds, though it does have a lot of improvements. it just doesn't have enough to warrant being considered an entirely new, fresh, innovative console. i has 3d, and it's improved under the hood. not saying other consoles don't do the same thing, just saying the 3ds is doing it, too.
