yea, but you can just map Ctrl-S to save if you save so much. Typically vim keeps swap files and save the file state there periodically, so you don't have to keep saving the file as you type. If the editor crashes, you can re-open the file and the editor will ask to restore it.
The power of the vim layout is editing speed versus emacs, in which commands and macros can be used in rapid succession to perform complex text manipulations in a couple of key strokes. If you really wanna try vim, you'd need to put in some effort (`vimtutor` can be useful to learn some tricks), but it'll be worth it :) (even emacs users know this, see `evil-mode`)
