The nice thing about Vim mode is that it glosses over latency by making simple edits take fewer keystrokes. It's sort of why vi was invented.
In the words of Bill Joy himself:
> ... you've got to remember that I was trying to make it usable over a 300 baud modem. That's also the reason you have all these funny commands. It just barely worked to use a screen editor over a modem. It was just barely fast enough. A 1200 baud modem was an upgrade. 1200 baud now is pretty slow.
> 9600 baud is faster than you can read. 1200 baud is way
slower. So the editor was optimized so that you could edit
and feel productive when it was painting slower than you
could think. Now that computers are so much faster than you
can think, nobody understands this anymore.
