That's why I learned vi back in 2004, and while I still get tripped up when backspace doesn't work in insert mode because of some terminal setting, using hjkl has become second nature. There's a lot to be said for absolutely having to learn something.
Once I learned enough to be proficient doing simple editing, I switched to using gvim on my Windows machines, and then learned more as I found myself wondering if there was a better way to do something. Now I do virtually all of my coding in vim. The only downside of this I've found is that I'll occasionally C-w when typing in a web form and close my tab instead of deleting the last word.
I never got interested enough in emacs to learn it, but if I find myself in a situation where it's what I need to accomplish something I'll learn it. Need is a powerful motivator.
EDIT: I should also note that learning vi[m] on a computer with a Sun layout keyboard makes the idea of switching into command mode a lot more palatable. Esc is right there next to the 1, rather than somewhere in the next state.
That said, after you get comfortable using insert mode with just the most basic command mode stuff, I would highly recommend incrementally expanding your use of command mode. Learn about yank registers, movement units (words, sentences, brackets, quoted text), how to repeat commands, how to record and play macro's, split buffers and how to move around buffers and windows, etc. You could start by adding one command or feature each week and go from there.
If you never invest time expanding your vim knowledge and habits, there really isn't much of a reason to use vim at all. The whole point of vim is that it has so many crazy productivity-enhancing features. If you don't want to spend time to learn any of them then just don't bother, but realize that no 'easy to use', fully GUI-driven editor could ever come close to the editing efficiency you can theoretically get using a command-mode editor such as vim. There really is truth in what people say, once you master the most useful aspects of vim, you can never go back.
