Just a reminder for the Sela Developer Practice Conference, on the 28th we're having a whole day on ORM:
We'll (Erez Harari, Ido Flatow, Gil Fink and myself) be presenting the following sessions:
Part 1 – ORM and Entity Framework
Part 2 – Comparing ORMs
Part 3 – Entity Framework Deep Dive
Part 4 – Real World Data Access with ORM
Part 5 – Best Practices – Experts Panel
Also I’m glad to say that Oren Eini has accepted my invitation to join our Experts Panel (everyone else but me are all about EF 4.0 so I need some reinforcement on the NHibernate side 
) so I’m sure it's going to be interesting.
Erez and I are going to give a P&P (Patterns and Practices) Lecture at the upcoming Sela SDP on the 28th of December.
ORM’s are great tools and they can give you a lot of value in your apps. But and there is a but, when mistreated they will just complicate things for you.
We are going to talk about some of the patterns that ORM’s are built upon and other patterns complementing the use of ORM’s.
And last but not least, a lot of Real World Code Examples and Demo’s(Yes, we are going to show code – so beware) of how this patterns are implemented and used.
