A Microsoft Office app for iOS devices was supposed to come out right about now, but it looks like the Redmond software giant is delaying the release for both iOS and Android apps until late next year.
Mary Jo Foley at ZDNet came across a roadmap showing this:
Gemini Wave 1.0 (October 2013): Windows Blue app updates
Gemini Wave 1.5 (April 2014): Office for Mac; Office RT refresh; Perceptive Pixel support; Windows Phone support refresh
Gemini Wave 2.0 (October 2014): Outlook RT; Office for iOS/Android
Microsoft is expected allow users of the Word, PowerPoint and Excel apps to access and view documents by default for free, after users log in with their Microsoft accounts, but editing functionality will be enabled with a paid Office 365 subscription.
Microsoft recently updated its SkyDrive iOS app, including support for the iPhone 5 and iPad Mini.
