I've been reading this thread with a growing sense of foreboding, which has in turn created a growing rage, and finally, resignation (literally).
I've been using EN since 2008 on Mac, Windows and iOS - but mainly on a Mac. It's never been been feature-level across all platforms but has been a joy to use - until now. I have a very slick (IMHO) GTD workflow that works for me. It involves using tags and only really works because I can see a lot of information on a small screen.
The release of 10 has blown that out of the water because of a UI designed for 5yr-olds and loss of features.
