lvm on a single big partition or just a single big partition?

Hello debian users,
                                                                                                  
Though I have used lvm for some time, I have one question that I don't                            
understand.                                                                                       
                                                                                                  
For one harddrive I often create a /boot parition that is not lvm and                             
create a huge partition on the rest of the harddrive for PV of lvm. Now                           
I am thinking what is the difference between doing partition like this                            
and just a single big partition without lvm?                                                      
                                                                                                  
Thanks in advance,
