Microsoft just released the Office 365 iOS application (iPhone only), allowing 365 subscribers to “access, view and edit … Microsoft Word, Microsoft Excel and Microsoft PowerPoint documents from virtually anywhere”.
Of note, Microsoft is currently running a commercial and online campaign touting the Windows 8 RT tablets’ ability to edit Office documents (they claim that the iPad can only read documents rather than edit them). It seems that Microsoft violated the letter of this ad campaign and the spirit while somehow still giving Apple folks a sub-par experience.
From the first look, it seems the formatting abilities are extremely limited – especially compared to other document editing iOS apps like Quickoffice Pro – but the integration with 365 will definitely be appreciated by subscribers of the service. In the meantime, you can find a quick gallery here:
