I don't use LVMs for the same reasons I don't "upgrade".  After using Linux for 10 years, I've got partition sizes pretty much dialed-in, at least, for me, and always custom partition.  I never let the installer decide.  It always decides wrongly anyway.

I never could see any advantage to LVMs (over "real" partitions) other than being able to resize them while they are mounted.
