I love my Office 365 subscription. It’s not only about Word, Excel and PowerPoint, but I also got 1 TB of space on OneDrive. If you compare solely cloud storage with competitors, like Dropbox, Microsoft’s solution is mostly the best. And as a bonus, you can have MS Office apps on all your devices, all up to date. There are another services included in Office 365 subscription, but I only need MS Office and OneDrive. I know that editing Word document on small mobile device may sounds crazy, but I use Word on my mobile phone, just not for editing files – I use it for viewing doc/docx documents from sources like e-mail when I’m on the go and I don’t have my iPad Pro with me. And Word for Android now reached 1 billion installations.
Android tablets are practically dead and using apps like Word on mentioned small devices is crazy. Is it worth for Microsoft to develop Word for Android smartphones? Yes, it looks like yes. Word is very popular on Android smartphones. If not, it would not reach the 1 billion mark for installs. Other Microsoft’s apps – Excel, PowerPoint, OneNote and OneDrive – are popular too with over 500 millions installs, but MS Outlook is not as popular with its 100 millions installs. Many Android users use their Gmail accounts with default client, so that may be reason why MS Outlook is not so popular.
Not all downloads of Word are necessarily downloads from Google’s Play Store. Some manufacturers preinstall MS Office apps as the result of contract with Microsoft.
In the past, Microsoft had its own mobile operating system, but development was stopped and mobile Windows 10 is no longer updated. Reason was minimal market share. Microsoft was changing things too frequently and broke its promises, like all devices running on Windows Phone 7.5 will get Windows Phone 8, but it didn’t happen. And later, Microsoft said all devices running Windows Phone 8 will get update to Windows 10 Mobile, but again, it didn’t happen. Market is dominated by Android and the only competitor is Apple with its iOS.
