Dropbox and Microsoft form surprise partnership for Office integration

The surprise partnership will benefit Dropbox users who use Office across desktop, mobile, and the web as Microsoft’s productivity suite will soon become the standard way to edit Word, Excel, and PowerPoint files stored on Dropbox storage. Office for iPad will benefit the most, with an update coming in the following weeks that will allow Dropbox users to link their account directly to the Word, Excel, and PowerPoint iPad apps.
