Using vim for the last 10 years or so.

Had switched to TextMate for about a year in 2005 when started doing Rails, but went back to vim quickly afterwards.

Tried to switch to sublime2 lately, but its far far from being ready. may be one day.

Vim is old. Way too old I'd say. And has absolutely hideous extension language, horrible internal API and looks like crap. Sadly nothing still comes close to replace it for me.
