I've heard that [Visual Studio 2010 = Visual Studio 2008 + Resharper](http://codebetter.com/jameskovacs/2009/01/19/visual-studio-2010-visual-studio-2008-resharper/). I'd like to know how true that is. I don't want to start using Resharper to accomplish superficial things, nor to accomplish things that VS 2010 now already handles. I'm sure Resharper 5.1.X offers features that VS 2010 does not have, but which of those - in your opinion - represent the true value-adds? Which of those "truly-valuable" features are available only in the licensed copy?
