That's an issue for the first month or few, but then it goes intuitive.

When it sunk in for me, I found myself combining operations in new ways without thinking about it. The situations where I really have to think about what I'm doing are usually when it's something weird like encodings or huge blocks of strangely formatted daily-wtf-worthy legacy code.

Sublime Text certainly has a lower upfront commitment cost to productivity, though. I still pop it open occasionally just because Ctrl-D is amazing.
