Indirect grammar is comparatively weak. It isn't "for consuming", it "consumes".

consuming content

No one "consumes content". They read, listen, watch, and play.

relaxed

A good writer conveys by action, not by description. If you say that a joke is funny, it is not funny.

portable

He wouldn't need to say this while holding the device in his hand. And he further conveyed this by describing the product's battery life.

So to conclude, Jobs would have said (and may have, I don't remember):

d) Here's a book (thumb, thumb), and here's a movie (play). Isn't that great?

Try saying that for your product.
