I don’t have any plans at this time. I will want to keep the book updated and maybe extend it or publish a 2nd edition but that will be up to the publisher to decide if it’s worth it.
Google is going all in on progressive web apps and currently working on native container support on ChromeOS. I wouldn’t be surprised if by the end of the year it’d be dumb to NOT have a Chromebook. Especially if Apple can’t stabilize macOS and keeps adding unwanted features to their laptops.
