You lousy kids, with your iPhones and iPads and iGadgets! Back in my day, we worked on real computers, with real keyboards, and mice with one button, and we liked it! BBEdit is a relative relic of that age -- when text ruled the Earth, BBEdit ruled text. And the old Mac app is still being updated. The latest version 9.5.1, adds in a couple of dozen fixes, and reverts some of the capitalization rules to the way it worked in a previous version. There are still some die-hards who swear by BBEdit for coding or editing text, and because of its power and versatility, it's $125 for an initial purchase. The upgrade to 9.5.1 by current users is, of course, free.
Nowadays, you've got your drag-and-drop and your touchscreens and your gestural controls, but BBEdit is one of the best apps that does what your computer used to be best at: editing text quickly and well.
