Air popped is like eating little packing peanuts - lacks the flavor. Cooking it on the stove top the way the OP describe yields the best tasting popcorn.
For something different, you can make kettle corn, or close enough to it using almost the same method, OP. Put your oil in the pan as usual, but add a couple tablespoons of sugar. As the oil heats up, keep mixing in the sugar until the sugar finally melts/dissolves. At that point, add your popcorn kernels & keep mixing until it pops.
