Office 2010 has reached the release to manufacturing (RTM) stage. The official launch for businesses is May 12, and the ship to retail stores will be in June.
Amazon and Best Buy are now promoting Office 2010 pre-sales, as is Microsoft's own online store. What's clear from Amazon's site is that customers who opt for a fully boxed version of the software over a download will pay a heavy price for the extra cardboard. The boxed version of Office 2010 Professional is $499, while the download is $349.
Microsoft is offering free upgrades to a comparable version of Office 2010 to customers who purchase Office 2007 between now and September 30.
Along with the desktop versions of the software, Office 2010 includes an online version Microsoft is calling Office Web.
