How exactly is it useful? I'm completely new to LVM...
Well, for example, suppose you run out of disk space. With LVM you can just add another disk, set it up as an LVM physical volume and then extend your existing volume group to include the new disk. You can then extend the size of your existing logical volumes to use the additional space. In effect, your original disk becomes the sum of the two disks. Much easier than all the shuffling around of data into different partitions that you'd need to do to add an additional disk without using LVM.
