While Chrome OS' offline usability has improved a lot since the platform's early days, there's no denying that an internet connection is still essential to get a lot of things done on a Chromebook. When you're away from WiFi, you can tether your phone's connection, but Google has a smarter ace up its sleeve: Instant Tethering. The feature started showing up two years ago to link two Android devices, was later one of the highlights of the Pixelbook announcement, then expanded to more Chrome OS devices. However, until now, you had to have a Pixel phone (or a Nexus) to set up Instant Tethering.
