There are many reasons to use class methods.

First of all, you need class methods to interact with class variables.

Sometimes a method makes more sense if it's associated with the class 
itself rather than with the instances of the class. For example, a 
method which escapes special characters in database queries would 
probably be associated with the database class and not with a specific 
database instance (representing a single connection).

Sometimes class methods are just for convencience. Compare

content = File.read 'C:/text.txt'

to

file = File.open 'C:/text.txt', 'r'
content = file.read
file.close

(Yeah, I know the block version. I'm using this as an extreme example.)
