The first time I fired up emacs was in 1995 on a pentium 66 with 8 MB of RAM. It made my computer grind to a halt so editing text was not going to happen. When I tried vi, it ran like I expected a text editor to run.
So here I am today, my fingers long trained up to use vi, and I find little need to learn emacs. Sure emacs has had useful features for years, but the barrier to entry was just too high, and now it is too late to win over folks like me.
