I finally installed Atom on my personal machine recently. I’ve been using it at work for quite a while now. I like it pretty well, save for some speed problems, bugs, and a few design decisions different from Sublime. Sublime Text had been my preferred editor for probably a couple years before Atom attracted me. I liked that it was pretty similar to Sublime but open source and visibly being actively developed.
I hadn’t switched at home at first because it didn’t support Snow Leopard, but after I upgraded my OS, it was sort of procrastination and holding onto the few things in Sublime I preferred. The polish of Atom and its plugins improved over time, though. The things I was missing in Sublime and just the difference from editing at work finally were enough.
I added config based on what I have at work to my dotfiles and made the switch.
