In over 13 years of coding I've never used a tool as buggy and crash-prone as XCode 4. I swear at it on a daily basis. I think they're mostly going in the right direction with the feature set but the fact that it's still this unstable after three point releases undermines my confidence in the underlying code base.
Have you been upgrading your Xcode installations or starting from scratch?
I got my Mac in 2010 and was having major Xcode problems with 4.x but I had to nuke my computer when 10.7.2 came out and I've had almost no problems since then with a fresh Xcode 4.2 install.
Not trying to apologize for Apple, Xcode does seem to have some serious problems, but figured I'd throw out how I "solved" my problems.
That's unfortunate. I'd be interested in knowing how many people at Apple actually use Xcode daily (and how many of those are the developers who actually work on Xcode).
Apple has grown a lot in recent years and I'm sure a lot of the new blood grew up on Xcode 3 but I've heard from friends that a lot of the old guard at Apple continue to use things like emacs/vim.
