There's a real danger I think in relying on a proprietary software program for something so key as text editing. For many developers, their editor will be with them for their whole career. Proprietary software has a tendency to not stick around. I hope to see Sublime eventually released under a free software license. I'd donate to that project.
I'm not sure I've seen a text editor that was revolutionary enough that I would consider myself crippled if it didn't stick around.
I'd be able to function without intellij ultimate but it would be incredibly painful and I'd permanently be slower.
