Well as you say an editor doesn't need updating that much. I used VIM for ages but had an hiatus in programming and when I came back I start using sublime. And now I switched back to textmate. Like textmate it's simple sufficient bundles. Looks pretty.
And with getting older. It's just an editor that makes me type text. Yeah yeah productivity but as I think more than I type it's not such an issue as long as I can do most of the basic editting ;)
