Editing a very large text file on an Android phone is not something that you need to do very often. But when you need it, you probably need it badly. A 12MB text file will choke most other editor applications. Vim does not blink. Nice!!! But you probably need to go to http://f-droid.org to get it. I do not think google play carries it. All you emacs fans out there? I can’t help you.
