I love Sublime and have been using it since the beginning of this year but I'm really worried about getting too "invested" in it because it isn't released under a Free Software license. My old emacs.d still sits in my home folder because I have this fear that Sublime will just stop being supported tomorrow and I would have no choice but to go back to emacs. I really just wish emacs had an amazing mixed mode, it's the only thing that even made me try out Sublime. All the php mixed modes I tried were really bad and I do a lot of work in PHP/HTML mixed view files.
