Impressed is somewhat ambiguous. I'm impressed by Eclipse - the degree of dumbness that results in a dialog box prompt following a run resulting in a compile failure that asks "Continue anyway" with a checkbox that allows you to skip the dialog and always run on failure completely baffles me!

So yes, I'm impressed by Eclipse, but in a rather bad way. I keep thinking "maybe that feature makes sense for Java", but even then a lot of the design seems at least weird, for not straight out nasty.
