That's not a new feature. ChromeOS has had app streaming since 2023. https://chromeunboxed.com/chromebook-app-streaming-guide-lim...

Similarly, the other features for the Googlebook are just normal features from Google's Android builds. The announcement is really that there will be a Chromebook Plus class of devices running the new Android-based ChromeOS, so everything in Android now comes to these devices for free, and apparently, most of the features from the current CheomeOS will be ported too. I just hope this means that Linux app support in Android will match Crostini by the end of the year.
