vi after 15 years

I've always managed to install my beloved XEmacs, or limp along on with gnu emacs, kate, kwrite, pico, or joe, but today after some 15 years using unix, I finally did it: 30 minutes of sustained editing with vi across several files.

The verdict? Not so bad really.

Years ago, why didn't I spend the 10 minutes it takes to get familiar with vi?
