Yes, you (and me as well).  But most people are quite unlike new and 
me.  There's a reason GUIs dominate today, and there are even a few 
kernel developers that don't use mutt for reading email.

Even for command-line-happy people, GUIs still have an advantage in that 
it is much easier to discover features by exploring the UI vs. reading 
manual pages.

Because you are only interested in your own itches (which is perfectly 
legitimate, but will keep perf's userbase down).
