Googlebooks lack the web app and Linux app support of Chromebooks

Googlebooks can't install non-compliant PWAs like Slack, while Chromebooks allow manual installation. Linux app support is also limited to a Debian terminal, with GUI apps not a priority for the initial release.

• Slack PWA can't be installed on Googlebook as it isn't a 'compliant' PWA
• Chromebooks allow manual PWA installation; Googlebook support is coming later
• Linux apps on Googlebook are limited to a Debian terminal environment
• Linux GUI apps aren't the main focus of Googlebook's initial release
