Choosing an all-purpose editor

Choosing an all-purpose editor

Having recently finished reading the Pragmatic Programmer
(http://goo.gl/UyKMTm) I've decided to try and apply some of the tips
described in the book, more specifically I've decided to apply one of the
tips in the book: namely to use one editor, and know that editor damn
well.
The weapon/editor of choice obviously is rather important, and I'd like to
avoid learning every feature of say notepad only to find out it doesn't
really cut it in the end (I guess notepad isn't all that configurable). I
really do not intend for this to be a 'Editor X is better than Editor Y'
kind of question, but instead a forum for people to discuss their editor
of choice - weighing pros versus cons.
I know that editors such as vim and emacs are a rather popular choice
among the more experienced programmers, and I am considering using either
one of them, but the learning curve is somewhat putting me off.
I've decided to go for Sublime Text as my all-purpose editor, only because
I feel like it covers the requirements of being configurable, extensible
and programmable and I like the way it looks and feels.
However, if anyone can give me any reason why using Sublime as my
all-purpose editor would be downright stupid, or whether it really is
worth it to spend hours upon hours learning to use vim effectively as
opposed to just hack and slash straight away with Sublime, I would really
appreciate it :-)
Cheers!
