OP, I been using LVM for everything but /boot and / for a while now.  I
have to say, it is really really nice to have.  When something needs
more space, it is easily resized and life carries on. 

Just pick the places where you can use it without adding any other
complexities you don't want.  Example, don't want a init thingy, put /
on a regular partition and normal file system, just make sure you won't
fill it up for a very long time.  Of course /boot has to be on a regular
file system too. 

Hope that helps.
