I've been using visual studio quite awhile now, and am still appalled that there is not good integration with any source control system. Subversion is only 3%!? Shouldn't every coder use source control? TFS doesn't count when CVS, SVN, hg, and git are all free and widely spread. VSS doesn't count either =P The subversion plugins are ok at best.<p>ReSharper adds a lot of features to VS that is standard in Eclipse and IntelliJ in the Java world, hence many people love ReSharper, esp transplants from the Java world.
