Note that this is not a prototype of the next version of MSDN... it is intended to be consumed by the internal browser in Visual Studio... so the non-IE issues mentioned in the comments and the lack of index/search/etc... are really non-issues considering how this material is intended to be used. I post it only to give a little bit more Whidbey information to folks who haven't installed the Community previews.... using it through a normal browser may not provide the greatest experience at this point :)
