Rule Of Thumb for => vs -> in Coffeescript
There are two preferred styles of programming in Coffeescript, closure based and class based.
In general you will use -> when using closure based style and => when using class based style, as the latter binds the this pointer to the current instance.
Also, when using => within a class be consistant, otherwise you will introduce hard to find bugs.

Or you can think of it like this,
any time you would normally do:
var that = this;
...
foo = function(){
doSomethingWith(that);
}do this
foo = => doSomethingWith(@)otherwise use a skinny arrow.
