Juval Lowy's thoughts on SOA

I have been reading a book by Juval Lowy and it is a pretty interesting read. Since the time I have been working on .Net and that dates back to 2001/02 I guess (1.0/beta days), I have been a fan of his various works. The simplicity with which he has explained the evolution of SOA in his book titled - "Programming WCF Services" - is just awesome. A must read for any software engineer.
