My company (with an IT department of close to 1K staff, of which a pretty big portion is developing in Java) is using Eclipse and Subversion (NOT subclipse) as company-wide standard. I and some of my colleagues are using ME and we love it.
It would be nice if ME support SVN also, and soon (I am not sure if ME works fine if I install the SVN plug-in because I don’t want to get stuck if it does not work; and have to do massive re-install again). Even if SVN may have faster release/patches cycle, as long as there is backward compatibility ME does not have to catch up with the SVN release. When more and more big companies are buying into Subversion (which seems to be a growing trend according to what their representative said) , it is a good strategic move for ME to support SVN. Sometimes we need to think outside of a developer’s usual working practice and mindset, and consider the need/support of companies.
