Presumably because ext4 is backwards compatible to ext3 grub didn't even
notice the change...

Ubuntu's pages list a number of improvements.  I guess I'm not overly bothered
about themes and the like, but maybe it does *something* I want.  I remember
the resistence to GRUB when we were all using LILO.

GRUB 2's major improvements over the original GRUB include:

Scripting support including conditional statements and functions
Dynamic module loading
Rescue mode
Custom Menus
Graphical boot menu support and improved splash capability
Boot LiveCD ISO images directly from hard drive
New configuration file structure
Non-x86 platform support (such as PowerPC)
Universal support for UUIDs (not just Ubuntu)
