In the old days, when Microsoft Corp. unveiled new software you might have gone to the store, paid for it once, and brought it home in a box.
But with Microsoft’s new service unveiled Tuesday, Office 365, the box is gone. It’s been replaced by a digital subscription that allows you to get almost everything you need from the web. In a promotional video, Microsoft CEO Steve Ballmer said the service offers a “complete office in the cloud,” which he touted as a major leap forward.
