My issue has always been one of muscle memory. The hjkl keys are fine to use when in Vim, but the majority of other products (browsers, word processors, spreadsheets, etc) don't support them for movement. So I have a constant context-switch in my muscle memory when moving between these different applications. On a Mac keyboard, I find arrow-key navigation with my pinky finger very efficient… only requiring the rest of my fingers to move from the home row when pressing right. I'm not sure this would work for everyone… but for me, one set of muscle memory is superior to convincing my nervous system to context-switch.
