The DS offers more choices for input. It doesn't require all of them to be used. And yes - certain games work much better with only buttons, some work well with a combination, and some work well with only touchscreen.
Don't sit there and pretend that having those additional options somehow destroys and voids conventional input. That's just silly.

Yep, it sucked for the first year as developers were trying to use the touch screen, microphone etc. rather than just making good games and using them as needed.
That's not the case any more for the most part. There's stuff like Zelda which I'd have enjoyed much more if it had traditional controls, but there's also stuff like the last castlevania which didn't use it at all, New SMB which barely used it etc.
Two screens, ignoring the input part also have their uses. For instance, having the map constantly displayed in Castlevania was a god send. I don't like when games get split across it though...like the Yoshi's Island sequel. But it has it's uses for sure.
