You should take a look at the consume-first (TDD) features of CodeRush. I think you'll find them more elegant, more efficient, and more intelligent than what you're otherwise accustomed to seeing in a developer tool (and running faster and with significantly less memory). So I say we let CodeRush respond to your assertion of whether Dev Express understands contemporary software engineering or not.
And if that fails, I suggest we settle this with a throwing contest. Whoever throws the other farthest wins.
