After rumor upon leak that Microsoft was cooking up a release of Office for iOS, you'd think its arrival would be celebrated with streamers and cake. Requiring an Office 365 subscription, the app is now available, and allows you to view and edit Powerpoint, Excel and Word files stored in the cloud, or attached to emails. Recently tweaked files can also be manipulated offline, and Excel and Word files can be created from scratch on your small-screen iOS device. You'll need an iPhone or iPod Touch running iOS 6.1 (there's no iPad version just yet), and the app is limited to the US at the moment, but head to the iTunes Store source link for the full feature list.
