I agree.  Having / on a fixed size filesystem isn't generally a problem.
I might even say /usr is also OK, unless you like to add lots of new
software.

That being said however, /home on a multiuser system will rapidly fill
up and having it on LVM so you can grow it on the fly is a "good
thing".  Also, depending on what your system is doing and how careful
you are about tracking things, /var (as in /var/log) on an LVM volume
can also be useful--logs can grow to be huge farking things.

Again, it rather depends on what you're planning to have the system do.
For the vast majority of home users, LVM is nice but not really
necessary.  On large multipurpose server systems, LVM is almost
mandatory!
