There is a lot of anticipation for Windows Phone 7, but little reason for new phone buyers to pick up a Windows Phone right now. Even with the extremely attractive and powerful HTC HD2, users won't be able to upgrade their devices to Windows Phone 7 when the new OS hits the market at the end of this year. Therefore, Microsoft has been working on sweetening up the Windows Mobile 6 environment by dishing out free software. Yesterday, the Redmond company announced that Windows Mobile 6.x users would be getting turn-by-turn navigation for free, today, Microsoft announced that Office Mobile 2010 is now a free upgrade for all Windows Mobile 6.5 users with the previous version of Office Mobile.
