Bill Gates gets himself an Android phone.

The billionaire Microsoft  founder told Fox News Sunday's Chris Wallace he recently switched to a mobile device that runs Google's Android software. The company officially killed off its Windows Phone line and software in July, due largely to dwindling consumer interest.

In the first quarter of 2017, Windows Phones' market share was 0.1%, according to a May report from market intelligence firm IDC.

Apple and Microsoft have been at odds for years. Its fierce competition goes back decades and was often showcased in TV ads. Gates said it's "great" Apple is continuing to do good work, but noted he still uses all Windows-based PCs. In the interview, he praised late Apple founder Steve Jobs, despite their famous rivalry.

In another news, Microsoft on Tuesday announced Microsoft Office 2019 will be available in the second half of next year. The big update will have more IT features and server upgrades to improve usability, voice and security, according to the tech giant.
