Example: the test automation tools into Visual Studio were terrible. Maybe they still are, I don't know, I've stopped using them. nUnit is just better. Their automated refactoring stuff may be OK, but the stuff from JetBrains is much, much better. Don't get me started on Team Frustration Server.
If they want to simplify and clean up their UI by starting with lower contrast icons to make the IDE background and the code foreground, that's totally a step in the right direction.
