I just recently switched to Sublime Text 2, and a after a solid week of coding in it, I must say I'm hooked. It's the best editor I've ever used.<p>I'm writing Boo, both client-side (Unity3D) and server-side (between Mongrel2 and Redis), and all it took was for me to drop in the Boo TextMate bundle and away we went.<p>The Boo bundle is outdated and needs some love, and Unity integration is missing, but Sublime is so nice that it really seems worth the effort of getting these things set up (when I can get around to it). For now, however, I'm quite happy with it.<p>Before the switch I jumped around (angrily) between Unitron (Unity's Smultron fork), Smultron, MonoDevelop (still sucks on Mac), GEdit (great editor, but GTK looks like shit on Mac), and tried several others without satisfaction.<p>Sublime is like a breath of fresh air.
