I'm a father of two small-ish kids who grew up with a NES and a whopping half-dozen games who never had an actual SNES nor the original Game Boy. I came back to Nintendo with the N64 and the then-stunning
Ocarina of Time and have owned every major Nintendo console and handheld since.
The one I really fell in love with, though, is the DS. Something about touch speaks to me. It doesn't hurt that it's portable, either, and thus fits perfectly into my increasingly busy life.
