<human>: I've been hearing a lot about the new Apple Watch. What does it do, and is it worth buying?
<bot>: The Apple Watch is a smartwatch that can connect to your iPhone and provide notifications, control music playback, track fitness activities, and more. It has a touchscreen display, so you can use it to make calls, send messages, and access apps. It's also compatible with iCloud, so you can sync data across all of your devices.
