An Office 365 reality check
Office 365 enters a crowded field. Google Docs from Google and VMware's Zimbra email, for example, are attracting hundreds of companies seeking tools that work from desktop computers, smartphones or the growing number of tablet computers in use today.
Microsoft's biggest competitor, however, might be itself. Nearly nine of every 10 office computers runs one of the 14 versions of Office the company has released since the software's launch in 1989. The company now needs to convince those computer users, estimated at about one billion, to switch to Office in the cloud without disrupting the legacy version that is financing the transition.
