     Hi emniger.
.
     su allows you to execute any command, and asks root password

     sudo allows the admin to configure with fine grain what users 
and/or lists of users are allowed to execute with or without typing 
their personal password.

     Even if you are the only user of your laptop, you may like to have 
some priviledged commands be executable without typing your password. 
Also, limiting the authorized commands brings you some additional level 
of safety.
