There's also Developing Web Applications with Haskell and Yesod by Michael Snoyman which is available from O'Reilly in dead tree format or for free in HTML format: http://www.yesodweb.com/book
It's a pretty good introduction to Haskell web development for people who are already familiar with both web development and Haskell.
Just make sure you have spacebar heating disabled.
You'd have to either use :find-file or :e (Ctrl-r +).
You can switch between buffers with :switch-to-buffer, :ido-switch-buffer, :b, :bn, and :bp. It's not the same as tabs though.
":" runs Emacs functions. Some commands from Vim have been added, but not all of them. If a function with the same name as a Vim command already exists in Emacs, it's not replaced. I'd imagine replacing the default Emacs functions could break things in weird ways.
:cd runs the Emacs cd function which behaves differently than Vim's :cd.
To get the equivalent of :tabnew, you'd have to use :buffer [name] and give the new buffer (Emacs's equivalent of tabs) a name.
There are a number of auto-completion plugins for vim. So even that isn't a loss. There's also Syntastic for syntax checking.
I found the biggest benefit of using vim is the fact that I don't have to switch between different IDEs for different languages. I can use vim for everything.
Manhattan and the trendier parts of Brooklyn have a rent problem, but most people commute from the outer boroughs, Long Island, and New Jersey where rent is much cheaper.
I learned Ruby because of Rails.
If I need a scripting language, I prefer Ruby because I know it the best now. I'm pretty good at Python, but feel more comfortable in Ruby because I use it more often.
Some people like Android more. Some people like iOS more.
