Another part of the discussion may be the fact that a large number of users are running dual (or multiple) boot systems, keeping the pre-installed Windows and adding Linux. Others will have Windows and Mandriva, adding Mageia.
While LVM may be nice if you are running one OS on one harddisk, it may be not so easy when running 3 OS on one harddisk. Or different installations of the same Linux (like stable version and cauldron). -- wobo
