Well, I’d agree if it was “annual”, but XCode really hasn’t chneagd much in the last decade. XCode 4 is the first real overhaul, and after griping about it a bit at first, I’ve come to realize that it’s actually pretty well thought out – all the things I griped about in my ignorance, they had actually thought of. Yes, the learning curve is a bit steeper than usual, but trust me, once you get used to its level of integration, you won’t want to go back.
