Amazon Echo is a wireless speaker that has a built in personal assistant. Just like S-Voice or Siri it can answer your questions, read you news headlines, update you on the weather, play music, or add items to your shopping list.

The device can also be controlled using your Android device or through a web browser when you’re not near the speaker.
Amazon Echo will cost you $99 if you are an Amazon Prime member or $199 for non-members, but at the moment it is sold with an invitation. At 9 inches high, it looks like a regular speaker.
