It’s been a good week for those had concerns about how much effort Microsoft was going to put into their "legacy" Windows Mobile OS. First we get an update to Bing, which includes a fairly significant feature upgrade in voice assisted navigation. Today, Microsoft announced Office Mobile 2010 in conjunction with the release of the desktop and web versions of their flagship product.

According to the press release, users of Windows Mobile 6.5 that have a previous version of Office Mobile will be able to upgrade for free through the Windows Marketplace for Mobile. Office Mobile 2010 adds support for Microsoft SharePoint 2010 as well as updated versions of Word, Excel, PowerPoint, and OneNote.
