sudo has better security and logging features than su (though these
don't matter as much on a desktop system where there is only 1 admin
and they have complete access). If you want an interactive session
using sudo you can use 'sudo -i'. The commands still go through sudo so
you get the finer grained security model and improved logging but don't
need the sudo in front of everything that needs escalated privileges.
Remember to exit when you're done :)
