I've been using codewarrior as an IDE (both C++ and java) for about 6 years after starting out on the Mac, then Windoze.

So far it's proven to be the best IDE I've played with and probably the only complaint is that sometimes it can be slightly flaky and quits or crashes (this is with Pro 6.0 and Java 7.0). I would guess that a lot of these problems will have been fixed in vers 8.0, but I'm still waiting to get the chance to use it!
