> Are there any other former vi/emacs users
Yes!
I also started my IDE days back in Turbo Pascal. Used most of the Turbo Pascal, C and C++ versions of Borland products up to Delphi early versions.
Thanks to some friends I also knew from seeing, not really used them, a few Amiga IDEs like DevPac.
When I started using UNIX, initially Xenix followed bz DG/UX and many others, vi was all there was available to us.
Eventually I found Emacs and it became my UNIX editor between 1996 and 2005. With vi playing the fireman role when nothing else was installed.
However UNIX wasn't the only system were I had to work on. So I became acquainted with Smalltalk and Oberon environments as well.
In the end, I kept always looking to replicate IDE experiences on UNIX systems. But never found one at the same level of experience than what the PC world had to offer me.
As my work became more focused in JVM and .NET land, I left Emacs.
Emacs might have been a great editor back in the day, but IDEs have so much to offer. Even if one can spend weeks coding ELisp code for the said functionalists they aren't as well polished nor as functional as what IDEs offer out of the box.

If one masters IDE shortcuts + mouse, I feel productivity is like playing a FPS against someone just using the keyboard.
