I don't care whether the help is in the browser or now, however the lack of a type-ahead index is a serious omission.  When I use the MSDN library, it's because I know what I'm looking for and I just want to get the reference sheet.  Usually I want to know the finer points of permissible arguments to a method.  I use internet search when I don't know what I'm looking for - I may know what I want, but I have no idea how to achieve it.  It's okay that the latter is online and hence relative slow - because it'll take time to sort through the information in any case.  But when I just want to look up a class or a method, search is not the answer.
