34" Ultrawide Curved Computer Monitor for $375.
It's the same price as the 27-inch model, has a really crisp 100Hz refresh rate (60Hz is standard), 3000:1 contrast ratio, 4ms response time, and 3440x1440 resolution (essentially like 4K, but ultrawide).
Amazon Echo Dot for $20.
It's an Alexa-powered voice-operated smart speaker.
We like ours for its simplicity and ease of setup, but prefer our Google Home Mini for its features and integration with Google devices like Chromecast.
