Engadget has 21 pages of these docs that were sent out - you don't need an account to read them. I thought that the most interesting things are multiple Exchange sync accounts supported, and remote wipe - even as a consumer, you can log in to your profile page and remotely wipe the device if it is stolen, etc.
