Microsoft CEO Steve Ballmer has confirmed Office for iPad is in the pipeline; however, its arrival will come after the touch-enabled version for Windows Modern environment is launched.
CEO Ballmer made this announcement during a speaking engagement at the Gartner Symposium in Florida, United States, today. Rumors of Office for iPad surfaced as earlier as in November 2011; however, they were dismissed by the company. Now, Microsoft has confirmed Office for iPad is in progress, and hints it will launch after "touch-first versions for our core apps in the Office suite" are made available.
Earlier this year, Microsoft launched Office Mobile for supported iPhones only, and this free download requires an Office 365 subscription before the user can use the application. At this juncture, the Verge noted that it is unclear if Office for iPad will require the same Office 365 subscription, or when it will be available. In June this year, we reported Office apps that run in the Modern environment are in the works for Windows 8.1, but there wasn't any official launch date made known. Hence, it appears that we would have to wait a while before Office for iPad is made available.
