Engadget has been covering developments with Microsoft bringing its Edge web browser, their successor flagship internet app to Internet Explorer, to iOS. I understand it is now available for iPhones (I don't have an iPhone, so I can't comment on that) and now a new beta for iPads. Why? Why is Microsoft interested in getting iOS mobile devices using Edge? Don't get me wrong. I'm all in favor of a greater diversity of offerings in any App Store, regardless of platform. I say "the more, the merrier." And I really do believe that Apple mobile device owners are, at least in theory, better off with another choice besides Safari and Chrome. But why is Microsoft doing this? It obviously costs money to bring Edge, presumably a free browser, to iOS for the first time. What does Microsoft hope to accomplish here? And why would I want to use Edge on an iPad? Is there anything about Edge that makes it attractive to iOS users? Does this mean Edge is destined to make a debut in the Mac App Store as well? Why or why not?
