It also takes a decision out of the mix when a user buys a new drive. They can
just dump it in the volume group rather than having to learn how to place it at
a mountpoint and migrate data (the actual commands are no big deal. Learning to
weigh the costs and benefits of applying your new 1TB disk to /usr vs /home

Its a usecase that matters to an interesting class of user: the petty power
user. They help Aunt Tillie with her computer. They built their own computer.
They think of themselves as quite tech-savvy. They are also liable to say
things like "If linux is so great why can't it even run normal programs?"

LVM is nice in that it accomodates this generally unpleasent sort of person
(who is much improved by education and has the potential to become a great
contributor once humbled and made willing to learn) though it does this by
offering a temporary crutch.
