It seems that all of my peers in the US (Oliver, Paul, Julian, etc.), are interested in XAF recently:-). Please check the latest blog from Seth Juarez (a PM for DevExpress Analytics division - follow him on Twitter at @sethjuarez):

I hope you like it and find it helpful, especially if you are not using XAF yet and considering its benefits for one of your future LOB apps. BTW, a more detailed and comprehensive getting started tutorial can be found at http://www.devexpress.com/Products/NET/Application_Framework/getstarted.xml
