"This pillow is soft, nice, modern, cheap and intelligent!"

Translation: Ez a párna puha, szép, modern, olcsó és intelligens!

[scotthensman]

I love it when my pillows are intelligent.

[vvsey]

As long as they are respectful, and don't talk back.

[DonFry]

Smart pillows? It was only a matter of time.

Wrong answer over one typo?

[Maureen98382]

Is "okos" an appropriate word to use in place of "intelligens"?

[p8888r]

I would not use them interchangeably, to me they are slightly different. Okos is more about knowledge while intelligens is about talent, something that cannot be acquired. If you talk about gadgets okos is used usually (eg. okostelefon, okosóra) but some manufacturer may refer to their product as "intelligent" and translation may keep that form.
