It's pretty well-established by this point that Microsoft's Exchange ActiveSync (EAS) is the standard connection protocol for mobile devices. It's probably the single biggest underlying factor in the rise of mobile computing and the bring your own device (BYOD) movement in business IT. Even BlackeBerry-maker RIM has begun to adopt EAS for some of its products, including BlackBerry Enterprise Service 10, to provide compatibility with Microsoft Exchange Server 2013 . A couple of infographics about BYOD landed in my Inbox this week. The first, produced by TrackVia from a variety of sources, makes the case that BYOD is already solidly entrenched in most businesses. Although much talk about this trend might see it more as a coming thing, the highlighted stat here is that 80 percent of employees are using personal devices for business purposes, even while only 53 percent of organizations report having an official BYOD policy.
