Xcode 3.x was nearly perfect. The Xcode UI went straight south in 4.x with this giant-window-always-the-wrong-size-for-everything design, that also sucked Interface Builder into the same app. That meant any crashy thing in IB took down your whole project, which never used to be an issue. If they back-ported LLVM to the Xcode 3.x GUI and restored IB as a separate app, I would be quite happy.
