If you have never heard of IT's Showtime before, you're in for a treat. Basically we video everything (technical sessions, demonstrations, events, etc) and post them up on the web.
We've just put the content from TechEd in the States up there http://www.microsoft.com/uk/technet/itsshowtime/ (you should still be planning on attending TechEd: IT Forum this November in Barcelona though).
Go have a look at what's available. If there's something you like, put some time aside and give it a try. Let us know what you think.
