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.
