Tablet Phone and Computer OS

Hi All,

So I was thinking about the way that different OS and devices get paired with each other:

Microsoft

Windows 8/RT: Tablets and Computers

Windows Phone: Phones

Apple

Mac OS: Computers

iOS: Tablets and Phones

Google

Chrome OS: Computers

Android: Tablets and Phones

So which one makes the most sense for you? Phone and tablet together or computer and tablet together?
