A lot of text editors have a 1% of emacs power but a great web site and a great interface. This help them to shine in the IDE/Editors jungle. So, this new interface, will help emacs (from a "marketing" point of view).
Personally, I think that Emacs is one of the best editors. Not so simple to use (you may think if you are going to start without a tutorial), but, definely... very strong and personalizable.
I prefer to not compare with IDEs. The advantages of IDEs is that they have a particular UI and a set of tools focused for a particular language/development tool. This will allow you to have an initial set of features. Ready to use. Without spending your time to work on personalization. You may think to IDEs as editors with a restricted set of features (compared with emacs).
Thanks for sharing!
