M.O.
He sounds very active, and very bright. Really, I don't think you have a thing to worry about.
Kids this age aren't at the stage of brain development to endow their toys with personality and meaning. There's this magical stage around 3 where they truly perceive their toys as being alive, but he's not there yet. Some toddlers (especially girls) like "manipulables" (stacking blocks, rings, and the like), but this is only one learning style, and it's not a requirement. He sounds like more of a kinesthetic learner -- he's thinking with his big muscles, and also like a visual and verbal thinker. Just because people think with their fingertips -- they're drawn to touch different textures, see how things are constructed -- doesn't mean your son has to.
Believe me, he'll be demanding every toy ever made in a year or two. Enjoy this stage while it lasts.
