I was surfing the web and stumbled upon an article with the title "The many flavours of Microsoft CRM". It is an article written by Carolyn April and she works for Redmond Magazine. Redmond magazine is the authoritative, independent voice of the Microsoft IT community, and provides real-world technical, product, news, and industry information for experienced IT professionals working within a Windows platform computing environment...yes thats a mouth full but thats what their website says.
Carolyn gives an overview of the power-of-choice you will have with the upcomming release of Microsoft CRM with the codename Titan. You can read the full article here http://redmondmag.com/reports/article.asp?editorialsid=408#2 and see what choices you might have with the current and the new version of Microsoft Dynamics CRM!
