You can use LVM for taking snapshots as well (very useful if you want to 
quiesce databases for the shortest possible time for backups) .  And you 
can use LVM to migrate data from an old drive to a new one or even to 
*shrink* a partition. I've never found LVM to 'be a pain'. 99% of the 
time it's invisible, and 1% of the time it's indispensable.
