the question is which issue do you run into more frequently
the need to resize anything other than the last partition on a disk (or have a filesystem span multiple drives)
the problames caused by LVM
for many of us, the cases where LVM would be useful are much more rare than the cases where LVM is a problem.
I almost never resize partitions after the system is created (especially on production systems)
I would not WANT to have a single filesystem that spanned multiple drives, that's what's known as RAID 0, and it means that if _either_ drive has problems, I can loose the entire filesystem.
meanwhile, the downsides have caused me problems more than once (including cases with colo systems where a drive has partially failed, the facility has replaced the drive and then 'helpfully' plugged in the old drive, now both have default LVM configs and the system is unusable)
