I'm finally catching up on some reading that I've been meaning to do.
Right now I'm reading 'Programming Windows Presentation Foundation' by Chris Sells & Ian Griffiths. Good read and I hope to finish it on my next flight 
Also spend some time this morning reading an article by Ted Neward on MSDN (http://msdn.microsoft.com/netframework/default.aspx?pull=/library/en-us/dndotnet/html/linqcomparisons.asp) which gives food for thought on LINQ and the whole OR-mapping issue.
