There was no analogue Pad Pro or analogue nub added with the DS Lite/DSi or anything though, because it simply wasn't as big a drawback as it was for 3DS.
But this discussion is all beside the point anyway.
DS aside, 3DS on its own merits is bad hardware.
I mean, that's kind of Nintendo's design ethos for pure handhelds. They were all built on affordable, already-dated tech. The Lynx, Game Gear, PSP, Vita, all were superior, more premium tech.
