In my opinion, relying on keystrokes for doing things is not a problem but a future. If you use Sublime Text very often and try to learn tricks you will find yourself touching mouse less and less.
The problem with Vim is that it is not designed for my shiny MacBook Air keyboard, it can't get benefit from all modifier keys other GUI text editors uses.
I don't know much about computer history, but I believe keyboards that Vim is designed for didn't have any modifier key but Escape. I guess they didn't have Shift too. That's why old programming languages are all uppercase.
If you want ⌘S, ⌘C, ⌘V etc., try Macvim (https://code.google.com/p/macvim/). I use it for longer coding sessions (more colors, faster rendering when in fullscreen with split panes), and terminal vim over ssh when working on a remote server. Also, I map Caps-lock to ESC on my mac, easier to reach (and who uses Caps-lock anyway).
They actually had META, SUPER, and SHIFT (someone please correct me if I'm wrong on which ones. I'm trying to remember which one came from ALT, and which one we now use the 'Windows' key for)
The point is, all modern keyboards basically have what keyboards have always had (unless you're counting those old Lisp machines or a 5250 for an AS/400 or something) 4 modifier keys.
