Microsoft has announced a new marketing strategy to increase the sales of Office 2010: giving the Starter version for free.
In addition to the free, browser-based Office Web Apps, Microsoft is also offering PC makers the ability to install a basic version of Office on new computers. The new program, Office Starter, includes a stripped-down version of Word and Excel. PC makers, retailers and Microsoft can all make money if the PC buyer later upgrades to a paid version of Office.
I have been using Office 2010 and I love it. The Beta has been very stable on my PC and once I got used to it I could come back to Office 2007.
