about IDEs and me:
i have been using vim for a couple years now. i've got some useful macros and still there's so much more to learn in vim. i love it. =)

about IDEs and co-workers:
my experience with co-workers that use IDEs like Eclipse, for example, can be illustrated with some typical examples:

they tell me, "hey, this IDE can do X", I yawn "sure, my vim macro can do this, too."
or "hey, this IDE can do that" - me: "nice idea, i'm going to write a vim macro for that."
"look, this IDE can do Y!" - .oO( what do i need Y for, when vim can do X? )
"look what eclipse can do" - i look, they click, eclipse freezes. *shrug* when i go back to my desk then usually i hear "now it works again!". (i have been suspected to have bad influence on computers running eclipse, because as soon as i stand in front of the screen, the program freezes)

just my 2 cents.
