So, I've had my Echo for a couple days now and really liking it. The sound is pretty good especially compared to our crappy under-cabinet radio/cd player. It's pretty amazing what it can recognize for voice commands. My wife is usually skeptical of the gadgets I buy (and I buy a lot) but she is loving this and wants to get another one for her mother for Christmas. Her favorite feature is the shopping list. She can just say "Alexa, add milk to my shopping list" and it will get added on her phone.
If you have music on Amazon it is real easy to play anything from your library (or Prime). It's been spotty on finding music you don't already have.
My favorite is the Flash Brief. When I enter the kitchen in the morning I just say "Alexa, flash brief" and she starts with NPR news and then whatever else I have setup (BBC, sports, tech, weather, etc...).
They are supposed to add more features later. One that I'm hoping for is to be able to connect to my Google calendar so it can tell me my schedule for the day.
So, for $99(prime) it's a steal. Not sure I would fork over $199 though.
Oh, my kids really love the 'Tell me a joke' feature. Her jokes are pretty bad but they get a kick out of it.
