I don't think we're really counting chromebooks. Hardware and software wise they're much closer to android tablets. While ChromeOS is Linux based it still uses ARM hardware and Android Frameworks. Macs are also closer to iPads hardware wise, because the new M chips are ARM based. Windows and Linux are OSes that run on virtually the same hardware (x86_64) but Windows is an ugly ad abomination of a bloated privacy violation while Linux just works.
