What do you need to do with LVM on a laptop that can't be done in another way? Probably nothing that you can't do, but I bought a machine with lots of storage

What do you need to do with LVM on a laptop that can't be done in another way? Probably nothing that you can't do, but I bought a machine with lots of storage space, spread over three physical devices, and I'm just accustomed to using LVM to manage things. It's not exactly a "Big Deal" or anything. Just something that jumped out to me based on my pre-existing biases.
