Want to get advice while you're plugging away at that big report in Office Online? You won't have to fire up a separate app (or website) any longer. As hinted at by recent leaks, Skype chat is now built into the web productivity suite's versions of PowerPoint and Word. If you want to share ideas with a colleague, you can keep the conversation running alongside your docs without having to juggle windows or browser tabs. Yes, Google Drive has had a similar option for a while, but this collaboration upgrade is definitely handy if you frequently work in Microsoft's world.
