Windows 8 970 Published by

Microsoft has spilled the beans on ARM support in Windows 8, but the biggest revelation is that this version of the platform will include Office applications



From v3.co.uk:
More interestingly, Microsoft stated that within the desktop environment, WOA will include desktop versions of the upcoming Microsoft Word, Excel, PowerPoint, and OneNote applications, codenamed "Office 15".

In other words, it appears that ARM-based devices running Windows 8 will come with the next version of Microsoft Office ready built in, a move that is almost certain to make Windows tablets a more attractive prospect to buyers than other devices, even perhaps Apple's iPad.
