Friend of mine who loves VIM recently switched from Ubuntu on PC clone to OS X on MacBook Pro. He doesn't use a mouse for anything, ever.
Just because the icons are there doesn't mean you have to click them. Sounds like you just need someone to show you how Mac keyboard customisation works.
You do have to change some keyboard accessibility settings, though, for the interface to be usable without a mouse (dialogs etc.). Out of the box, you can't use OS X with the keyboard alone.
VIM is an editor. I'm talking about the whole desktop environment, especially the windows, also tried to set some keyboard shortcuts while I was using the Macbook Pro my company gave me.
I know what I am missing (a useless, pretty looking hipster GUI) but have never seen an Apple user who knows what he misses.
I'm talking about the OS, not an editor. If you have to touch mouse or trackpad ever, you're doing it wrong.
As noted elsewhere though, you do need to turn on keyboard accessibility. And as for what's missing--window sizing. That's a free or $10 add on depending on how slick you want it.
