Create a Wireless Office Using Windows Mobile | Smartphone and PDA
"Until now, Windows Mobile devices were not able to open the new XML-based file formats (.docx, .xlsx, and .pptx) introduced in the desktop PC version of Microsoft Office 2007. But with the new Microsoft Office Mobile 6.1 upgrade, users can open documents saved in the Office 2007 format (Fig. 1), and save new ones in that format. The software also features new functionality, like enhanced charting capabilities in Excel Mobile and the ability to display SmartArt and themes in PowerPoint Mobile (Fig. 2). But, for most users, the compelling feature will be the ability to work with Office 2007 documents if your company is already working with the newest version of Microsoft's Office suite. "
"Microsoft Office Mobile 6.1 is available for Windows Mobile 5 touch screen devices with a build number higher than 14847 (tap Start >Settings >About to find your build number) and all Windows Mobile 6 devices (touch screen and non-touch screen). The upgrade is available for free for some users, and you can find out if you're eligible by visiting Microsoft's Web site (microsoft.com/windowsmobile/en-us/downloads/microsoft/buy-office-mobile.mspx). Otherwise, you can purchase the upgrade at handango.com for $49.95 (search for "Microsoft Office Mobile")."
