You're assuming I don't ever use one of the other IDE's. I've used Eclipse on occasion (currently using it somewhat on Android development as a debugger) and I have to open up Visual Studio at work on occasion.

Neither is better for me than vim and unix tools, even if I have to run under cygwin. It's cool that jetbrains is making something new, I just wanted to point out there are few (if any)features vim and/or emacs do not have.
