Your exactly right, with the fact that those features serve 1 purpose and 1 niche.

To clear a little confusion by what I mean on unrefined products, I can think of a prominent Swiss Army Knife...Google.

If I asked you to convey to me what is Google as if I didn't know, you'd probably say they're a search engine. While I don't mean to discredit all the products Google has, they themselves have been known to kill off their own products (Reader, Checkout, Buzz, Wave, ect) to refine a centralized purpose (ex. if you sign up for youtube, you now have a google plus).

This is the art of the niche, bringing multiple features to form one cohesive purpose.
