Nothing keeps you from doing it that way, but many of us have gotten used 
to (and comfortable with) the abstraction layer possible with LVM.  Never 
had any problem with it, and happen to like it.

With grub and grub2, there is no reason to put /boot in a separate 
partition.  That goes back to the days of LILO, when it could only read the 
first xx megabytes of a disk drive.  Both versions of grub are quite 
comfortable reaching to the back of a big disk to pull up your /boot files.
