Update (7/22/19 @ 12:23 PM ET): As promised, Google is rolling out Bluetooth Fast Pair to Chrome OS devices.
Last year, Google unveiled a feature along with the Pixel Buds called "Fast Pair." The feature is part of Google Play Services and it works with Android 6.0 and above. Fast Pair enables quick discovery and pairing with compatible devices via Bluetooth LE. Now, it's getting even smarter and will soon support Chromebooks.
Fast Pair was created to improve the experience of connecting Bluetooth accessories to smartphones. It did that in one way by speeding up the process. However, it's still annoying to set things up for the first time on a new device. Bluetooth devices connected with Fast Pair will now sync to your Google account and be remembered on your "current and future Android phones." This will make the phone set up process even smoother.
The other big news with Fast Pair is Chromebook support. Google says the feature will be coming to Chromebooks in 2019. As we see more tablet/laptop devices ditching the headphone jack (such as the Pixel Slate), Bluetooth is even more important for Chromebooks.
Lastly, a bit of good news for the ecosystem, Google is working with Qualcomm (and others) to add Fast Pair support to SDKs. This will make it easier for manufacturers to create compatible products. Expect to see more from brands like Anker and Bose in the near future.

Update: Chrome OS support rolling out
Back in November of 2018, Google announced a few features for Bluetooth Fast Pair. One of the big plans was support for Chrome OS devices. They said it would roll out in 2019 and users are starting to see it show up now. Reddit user spen3000 shared the screenshot above of the Pixel Slate on Chrome OS 76 beta. The headphones shown have been Fast Paired with the Pixel 3 and now they are automatically being listed as available on the Chromebook.
No one else in the Reddit thread has mentioned seeing the feature, so we're not sure how widely this is rolling out.
