I use it, love it, and swear by it. Didn't know how much I would love it until I got it. Now I'm refusing to go to orcas until they do.
Runs great on my machine (AMD athalon 64X2 2 gb memory.)
It does take a while to grow on you though. Expect to have the training window open for a while and learn how to code "the code rush way."
I also love the references window, which I keep open on the right hand side of my wide screen monitor. Nice to be able to just glance over and see where the identifier under the caret is used. Gives a very intuitive, and admittedly error-prone, "am I making
a big change or a small change" feel.
Code rush is of course only half the story, Works best with refactor which blows VS 2005 out of the water. Not only more refactorings but lots of tiny useful ones for "just cleaning up code" with less risk. I love the one hotkey "what refactorings can
I do here?" feature.
Anyway for more gushing read their promo literature. But these products have made me much more productive and are very plesant to use,
