Back in July, we saw some snippets of code buried in Chrome OS that suggested Chromebook owners would soon get the chance to send SMS messages from their laptops through their Android phones. Well, it looks like the feature is arriving with Android 8.1.

The Android code hints at the same feature - SMS Connect - and this time there are accompanying messages that show how to set up the feature. For now it doesn't seem to be working (Android 8.1 is still in beta) but it's a good bet that the functionality will go live soon (maybe something to consider if you're in the market for a new laptop).
