UEFI (EFI) is much more than a graphical "sheen" over the BIOS. It is not a BIOS at all. It is simply UEFI = Extensible Firmware Interface. UEFI is not defined to be graphical at all. It can look like an old BIOS if desired.
UEFI has many Many advantages:
1. Full 64 bit computing starting at the Firmware (UEFI). No more 16, 32 bit, Legacy BS
2. Full 64 bit address space at the Firmware level.
3. EPU stuff at the Firmware level independent of OS.
4. Firmware and OS can communicate directly and easily in C language or in BYTE Code (think Java). It's called EFI Byte Code. No more Assembly, legacy BIOS calls, DOS crap.
5. UEFI is parallelizble. Code can be executed simultaneously. Devices can be initialized in parallel.
6. No weird limits like the 2TB / MBR, ...
7. You can easily write your own UEFI apps. Diagnostic software. I'd say hopefully soon we'll have some pretty cool UEFI software we can use.
8. 100% file based. No more MBR, no hidden boot loaders lurking in the MBR. No weird hidden crap at the start of Windows partition.
