Yes was going to say on android I've been using SMS and WhatsApp messages from my computer for years too. Mac, Linux, Windows, Chromebooks all integrate seamlessly and nicely so not sure what the issue is?
Moreover, it's largely irrelevant - the topic of the article was using a keyboard without having to drag around a laptop/desktop. If someone replied to a text on their MacBook, they'd have broken that constraint
My main driver is macOS + Android, and I certainly wouldn't say Android SMS is "seamless", Google Messages for web is a pretty significant downgrade from a native app even if using an unofficial desktop app: https://github.com/OrangeDrangon/android-messages-desktop
