With today's triple launch of Windows Vista, 2007 Office system and Microsoft Exchange Server 2007, Microsoft has started a real new day on his history (and on our business too).
Office 2007 is actually not only a suite of products, but a complete and integrated platform for collaboration, totally customizable and "developable" (developers will have tons of opportunities to make business on top of the new architecture), while Windows Vista is the first sign of the new movement on the future.
"Better Together", this is the word to remember...
