Here is an

interesting interview of Rob Harwood
, one the main IDEA developers.  In
this piece, Rob discusses mostly IDEA, but his remarks on Eclipse are respectful
and well balanced, which is quite a change from what we usually hear from the
"third IDE" advocates out there.  He also discusses Swing/SWT, components,
the Open API, etc…

My preference for Eclipse is probably well known at this point, but I have
the utmost respect for the JetBrains guys, who not only manage to keep up the
pace against Eclipse, but are actually still able to sell a product while
competing in a free (as in "no money") market.

Congratulations, guys, and keep giving Eclipse a run for its money!
