>If you search Linqpad on Youtube there is a nice 42 min presentation Albahari gives on Linqpad. Interesting if you haven't seen it.

I think I have seen it (try www.linqpad.net and its links - there is a wealth of information + link to some videos one of which I think is the same as the one you mentioned). For example I didn't know that I could do EF queries until I saw EF video there:)
