We've already seen Microsoft's Universal Office apps hit tablets, laptops and desktops as part of the Windows 10 Technical Preview, now the company has announced they'll be headed to phones by the end of the month. The Universal Office apps, which so far include Word, Excel and PowerPoint, are meant to show off a new touch friendly version of Microsoft's long-running productivity suite. But they're also an example of how developers can build one app that easily runs across a variety of Windows 10 devices. On phones, the Office Universal apps highlight the content of your documents, with typical commands and controls at the bottom of the screen. Microsoft says that should help with editing documents one-handed. On tablets, the Office apps look more like the full-fledged Office 2016 desktop apps, but with a interface tweaks to make them easier to navigate with your fingers.
