It's not much fun to plug away at a presentation, but Microsoft might have found a way to make the experience more bearable for Office 365 subscribers. It's updating the Windows version of PowerPoint with real-time collaboration that helps you share the workload. You can see who's editing specific slides, and see typing as it happens. You'll need to be part of the Office Insider program to use this right away, but don't be surprised if it's available more broadly in the near future.
Microsoft's updates will also let you know what's going on when you're away from your desk. Both Android and iOS users are getting notifications that let you know when someone is offering or working on a shared Excel, PowerPoint or Word file. Ideally, you won't be caught off-guard when a coworker starts editing a team report. You'll have to be patient if you think these would be useful, however. You need to be an Office Insider to get these notifications on Android at the moment, and you'll have to wait for the December updates before they show up on iOS.
