I have been waiting for someone to create a Vim control scheme that relies on WASD movement and maybe also brings in other common gaming related keys (E for insert?, space for escape?) To me this seems more logical than hjkl/i/esc.
Until then though it just feels like more work that it needs to be for me to personally learn Vim. Which is a shame because I can recognize how useful it can be, especially after watching Destroy all Software screencasts.
