|XP's Boot.ini = Vista's BCDEdit...|
The reason you just don't hear about BCDEdit as much is a no-brainer:
While several folks who felt at home with XP may have embraced Vista, there are still many more that are cautious about the OS, let alone installing & using it extensively.
The ones that have--myself included--don't even bother with the (strictly command-line) file when--for all intent & purposes--less convoluted programs like Vista Boot Pro & EasyBCD are out there & available for FREE to manipulate the BCD stores.
