That's a silly question. Of course it knows your current
position--it just chooses to modify your position when you exit

i and a are two of *many* ways to enter insert mode. I'm not sure
all of them are completely justified (I've never uses s or S, for
example). I typically use o, O, i, I and A the most. I don't have
much use for a.

The existence of command mode allows plain old keystrokes to be
commands--it potentially makes commands easier to type. Emacs
users don't find it to be a compelling advantage. ;)
