We use a lot of open source Java software at work, and we seem to spend half our lives in Eclipse. Not only do we use Eclipse as our development environment, but we use their Java GUI widget set (SWT/JFace) for our user interface.
So it was a nice suprise to see that Eclipse 3.3 has finally been released. I've been using pre-release versions of the SWT/JFace destined for Eclipse 3.3 for months now in our product, and on the Mac platform (which is what I use as my desktop), as I found it to be more stable and layouts to be more compatible with Linux and Windows implementations.
So here's to the Eclipse people - good job guys, thanks a lot.
