Microsoft has released Office Mobile for iPhone, a mobile version of its Office productivity suite. The suite is limited to Word, Excel and PowerPoint, and the latter one does not offer edit capabilities other than adding notes. The programs are also quite limited in functionality, and probably the biggest caveat is that you need an Office 365 subscription, which costs $99.99 a year. More details can be read at MacWorld.
Don’t confuse Office Mobile for a full-featured version of Microsoft’s Office suite. You can use the app to view and edit Word, Excel, and PowerPoint files. You can even create Word documents and Excel spreadsheets on your iPhone, though not PowerPoint presentations. Documents, spreadsheets, and presentations look on your phone like they do on your computer screen—though smaller, of course—thanks to the app’s support for charts, animations, SmartArt Graphics, and shapes. You’ll access those Word, Excel, and PowerPoint files from SkyDrive, SkyDrive Pro and Sharepoint.
Microsoft put in some nice touches aimed at mobile users. Word and Excel both feature Viewing Tools that let you jump to specific areas of documents and spreadsheets, saving you from an afternoon of unending scrolling. In PowerPoint, a Slide Navigator performs much the same feat.
