Windows Cloud, outlined briefly by Microsoft CEO Steve Ballmer at a conference in London this morning, is a separate project from Windows 7, the successor to Vista. Ballmer didn't say much, claiming he didn't want to spoil the official announcement. But he made it clear that sorry, no, Microsoft won't be moving to a fully browser-based version of its Office applications. Rather, Windows Cloud will let road warriors do what Ballmer called "light editing" at, say, a public Internet workstation or kiosk. Ballmer dubbed the concept "software plus services," as opposed to a full software-as-a-service product. Sounds like the plan is to do just enough to keep Office customers from switching to Google Docs. (Photo by AFP/Artyom Korotayev)
