I'm no longer an MVP this year so won't be there but as a heads-up to foregetful techies , you can get UK-US socket adapters at the luggage shop (name escapes me) that is just down the street from the convention centre.

Also - as a heads-up to any Seattle based muggers, there is usually a small crowd of techies with their laptops standing outside the luggage shop just before opening time on the first morning of the summit :-)
