The new Office apps are universal, offering a unified experience across smartphones, tablets and desktop and laptop PCs, Microsoft has demonstrated.
The next step
"Over the past 12 months, you've seen us reimagine the traditional Office experience for a mobile-first, cloud-first world," Microsoft Office Product Management General Manager Julia White wrote in the post.
"The next step in this journey is the delivery of touch and mobile optimized versions of Word, Excel, PowerPoint, OneNote and Outlook for Windows 10," she continued.
The apps will be installed out of the box on phones and small tablets (meaning sub-8-inches), and available as a download on other devices. In addition they'll will be available with the next Windows 10 Technical Preview, arriving "in the coming weeks."
