The intro/starter deck(s) are meant to be an interactive tutorial for two players. They basically do the same thing Origin/Duels's tutorial does, but needs two players (or you to play both sides and see how it's done) and only have 40 cards. Unless I'm reading you wrong and you're thinking theme decks which are a step above that.
No, intro decks are just single decks that have 60 cards. Here's a list of the ones for Magic 2015.
Anyway, intro decks are fine beginner products. You get a deck with a theme you like, and you can adjust it with your own collection of cards. They are usually weak (but fine for casual play) but provide a good framework for deckbuilding.
