New Microsoft Office for iPhone released

Microsoft is releasing new, beefed-up versions of its popular Office software apps for iPhones and iPads, part of the company's push to stay relevant to workers in an increasingly mobile world. It's also working on new versions for Android tablets and phones, although they're not yet ready for general release.

As more workers use smartphones and tablets along with — or instead of — desktop PCs, they want to have the same capabilities on all their devices, says Michael Atella, director of Microsoft's Office apps product management. Microsoft has been working for the last two years to build new web-based versions of its software and apps that can be easily used on the much smaller screens of mobile devices, but still seem familiar to people who use the traditional desktop tools.
