The Daily reported today that Microsoft is working on an Office app for Apple iPad. This should not surprise anyone but I highly doubt their timing of release. The Daily also added that the app will be released in coming weeks and the app suite will feature Microsoft Office apps like Word, Excel, PowerPoint with editing options as well. Windows On ARM devices will get released only in Q4 2012, Microsoft Office will be one of the key USP of those devices. So, I doubt Microsoft will release the same for rival platform before their own platform alternative is ready for public sale.
Anyway, let see how Microsoft plays this out.
