I've been using Linux distributions since the end of 2012. I use different *nix systems on my various machines:
ElementaryOS is another Linux distribution (Ubuntu-based) that I like and have used in the past.
I spend a lot of time in terminal, and that's why I like VIM.
If you're on Ubuntu (or one of its derivatives), just do a
sudo apt-get install vim
and you'll have it.
As GTK theme I use Flattiance, a fork of the Ambiance theme (the default Ubuntu theme).
As terminal emulator, I use
gnome-terminal, themed with the flat terminal theme.
