Over on the Office blog there have been a couple of announcements. If you’ve got an Office 365 subscription (A3 or A4, or the Office ProPlus subscription and others) then you can now get Office Mobile for Android Phones and the iPhone!
Office Mobile is the official companion to Microsoft Office. Word, Excel and PowerPoint documents look great on your phone, thanks to support for charts, animations, SmartArt Graphics, and shapes. When you make edits or add comments to a document, the formatting and layout remain intact. When you return to your PC or Mac, your document looks like it should.
Annoyingly the Android version is not available in the UK yet though - 'more countries coming on board over the next several weeks' according to the Office News post.
