These "I've used vim/emacs and decided to try switching..." articles always leave me cold.
I mean, both are insanely powerful editors. It's not as if there is something one can do that the other cannot, and if there is, it's doubtful that a user would want to -- for example, I don't think vim has a built in email client, but the vim users I've talked to laugh at the idea of an email client in their editor.
As a result, all of these "I've switched" articles begin with a comparison of modal and non-modal editing, discuss some pros and cons of both, and end with the same conclusion: both are great editors!
Where's the beef?
