Vim Smackdown

Intro / Ethos

• Vim vs Emacs: seems like comparing a text editor to the JVM. Apples to oranges?
• Where Emacs is about providing the user powerful tools, Vim is a powerful text editor focussed on efficiency
• Emacs has nice tooling for clj dev - can Vim match it?

Keep the mnemonics in mind...
