5 important things we still don't know about Google Home

Google Home, which was unveiled last Wednesday, is designed to be a direct competitor to Amazon Echo.

Amazon Echo has become extremely popular since its initial debut two years ago. It's a big Bluetooth speaker with a ton of built-in microphones, which lets Echo hear you and speak to you. Just plug it into a wall and it's always on.

You can use Echo to play music, set alarms, and add items to your shopping list, but you can also ask it questions about movies, culture, sports, and more. It's constantly getting new features all the time.

Google Home will work almost exactly like Amazon Echo: Just plug it into a wall and boom, you have a personal assistant that's always on and ready for your command. Google Home looks like a pretty cool product, but there's still much we don't know.
